Question

Based on the evidence provided in this lesson, explain how you can tell if a process is exothermic as written.

Ronald Prasad · Accepted Answer

based on the evidence pride in this lesson. How could we telephone processes exo, thermic as written. So in exo thermic reaction will release energy or heat to the surroundings. So if we have in equilibrium, reactant and equilibrium with products, the an therapy would be written on the right hand side. And this would mean in the forward direction that this is exile, thermic as we are releasing heat so we can usually tell if it&#x27;s extra thermic as written if the entropy, the Delta H here, is on the right hand side.

David Collins · Answer

two words that describe the process are endo thermic and exo thermic. If a process is endo thermic, then that means heat is absorbed as the process occurs. If it&#x27;s exo thermic, then that means heat is released as the process occurs.

Marissa Turner · Answer

is this question 44 from chapter 10 section for and in previously mentioned exo thermic reactions are the driving force. But why is one melting? Um, a nice Q two liquid toe water, an endo thermic reaction. Okay, so exhausts for make means it is releasing heat and in togther make means it is absorbing meat and room convictions is about, like, you know, 25 degrees associates and that is higher Then it is an ice like an ice cube stage, which we know is like raising and industry make reactions happened and when he is absorbed by breaking down the structure So Indo thermic is going Teoh cause breaking down of ice cubes, crystal structure and this is from an increase connect energy cause we also know when there is an increase. You can energy particles move faster and we don&#x27;t know at the in the liquid, a liquid state has faster connect energy than a solid state. Okay, so this is gonna transform it to a liquid. Okay, water and the surrounding area. Um, we&#x27;ll have the heat to start melting the ice, that the melting process and this is basically because they&#x27;re strong here. There&#x27;s only there&#x27;s a a greater temperature, Senator, is when the water for you. Oh, no. Also in a liquid. Not gonna have a greater can. I want you to have a greater temperature. Then it is. And I said I have to absorb this heat. So this is why transforming and ice to liquid is endo thermic.

Ronald Prasad · Answer

the law, a conservation of energy states energy can neither be created or destroyed. Energy can be transferred from one object to another, and it can assume different forms in and energy exchange. Energy is transferred between the&#x27;s system and these rentals. The system loses energy. These surroundings gain energy and thanks person in chemical on physical changes matter often exchanges energy with its surroundings. In these exchanges, total energy is always conserved.

Amy Jiang · Answer

do we have before here? So this is absolutely everything. And this is our product and are reacting. And our change agent, because you&#x27;re tuned to bury three killed, you and it increasing. So if our reactant came from or reactions to our products, the change in H is 233 pillage ALS, which means it increasing. And it our products have an additional 283 killed jewels of, um underneath. That means our products have more energy, which means that this reaction is handled. We need to provide it as a d in order for a product hooker.

David Collins · Answer

to determine whether or not each processes eggs, a thermic or endo thermic and the sign on delta age, we need to know the direction in which heat flows. If heat flows into the system then it is endo thermic. If heat flows out of the system, warming the surroundings, then it&#x27;s eggs a thermic. So if natural gas is burning on a stove, heat is flowing out of the system, warming the surroundings. So Delta H. Is negative and this is an X. A thermic process. If we have isopropyl alcohol evaporating from the skin in order for it to go from a liquid to a gas, energy needs to be absorbed or heat from your skin needs to be absorbed. This is why your skin cools when isopropyl alcohol evaporates because it takes heat from your skin. So the process is taking heat from the surroundings your skin. Thus, it is an endo thermic process and delta H is positive. And for the last one, if water is condensing from steam, steam is a gas phase. When it condenses, it goes to hey liquid phase, a gas phase always has more energy or heat than a liquid phase. Therefore, heat is being released from the system from the water as it condenses from a gas to a liquid. Because heat is being released. This is an exact thermic process and delta H is negative

Problem 2 Easy Difficulty

Based on the evidence provided in this lesson, explain how you can tell if a process is exothermic as written.

Answer

An exothermic reaction is characterized by the release of heat.
Increase in temperature favours the formation of substrates in an exothermic reaction.
