Question

If the internal energy of the products of a reaction is higher than the internal energy of the reactants, what is the sign of E for the reaction? In which direction does energy flow?

So there&#x27;s questions. Ask emails that, uh, the year of our products. It&#x27;s ironed, And, uh, the Internet energy have a pervert tired and Internet. And we have a reactant that what is day sign homed in Delta. He helped the reaction. So he d, uh, Internet Hannah G of a broader to hire them that would react. So I can&#x27;t see any of products. You suppose to, uh, g make your brothers and the energy of reactions. It&#x27;s a cost to you have. Okay, so that&#x27;s how he will be. He wants to e t minus. Lee are So you put it aside and reactions, then Disa very positive. So the doctor, he will pass to you on here. Delta. He is positive. That means that each Oh, Kenny G is flowing. Roamed sea stem to the surrounding from system to surround them. Uh, I&#x27;m sorry. Eat his friends from the from the surrounding into the sister Sani into that system because they don&#x27;t. Hey, it&#x27;s possible this kind of reaction the reaction best become cold because the absorb heat from the surrounding

If the internal energy of the products of a reaction is higher than the internal energy of the reactant, then what would the sign on delta E. B. The scenario would be something like this. Where if we are representing the energy by height, the energy of the products is greater than the energy of the reactions. In order for this to occur, then energy must flow into the system, the system being the chemical reaction as energy flows into the system, then the products end up having a greater energy than the reactant. The energy can be described several different ways. One way to describe it is a change in internal energy, which is delta E. If we are having the system, the reaction itself have a flow of energy into it, then we will have an increase in internal energy and the sign on delta E is going to be positive.

So this question says we have a chemical system, so this will be our system and we have energy e flowing out of the system and asks, What&#x27;s the sign off the energy in this system? And so in this case, if we have energy flowing out of the system, our East system will be less than zero, meaning it&#x27;s negative. And so the sign will be negative. And the reason for this is that our system is losing energy and it&#x27;s being gained by the surroundings, and so are east System is less than zero. However, R E surroundings in this case would be greater than zero or positive because because the surroundings would be gaining any energy that the system is losing.

Charotte Mcadam · Answer

so the energy change in a chemical reaction is due to the different amounts stored chemical energies between the products on the reactions. So it&#x27;s stored chemical energy, otherwise known as the heat content off the system is also known as pencil p. So here we are, considering if energy flows out of a chemical system and into the surroundings, What the sign off our change in energy of the system. Maybe so. This change in energy will be a negative sign.

Charotte Mcadam · Answer

So somehow chemistry is the study off the heat energy that is associated with chemical reactions and or physical transformations. A reaction may release or absorb energy, and a phase change may also do the same, such as in melting or boiling. So in this podcast, we would just be considering on energy exchange, where we have a chemical system that&#x27;s absorbing energy from its surroundings. So the change in energy of the system is a positive process. This is because is depositing energy. Therefore the quantity increases.
