concentration Discuss the two conditions that are required for a chemical reaction to occur, and explain why an increased temperature increases the rate of reaction. (in reading) increases rate of collision, frequency, more opportunities to react.

Step 1
**Collision:** The reactant particles must collide with each other. 2. **Sufficient energy:** The colliding particles must possess sufficient energy (activation energy) to overcome the energy barrier and break the existing bonds to form new bonds. Show more…

Question 1 (1 point) In what way(s) does increasing the temperature cause an increase in the rate of a reaction. Please select all that apply. Do not guess. Right answers will have wrong answers deducted from them. Increasing temperature helps randomize the orientation of molecules promoting collisions. Increasing the temperature breaks covalent bonds aiding in leaving group velocity. Increasing the temperature increases the energy with which the molecules collide. Increasing temperature increases the number of collisions per unit time. Question 2 (1 point) What are the necessary conditions for a reaction to occur. Select all that apply. Do not guess. Wrong answers will be subtracted from right answers. The reactants must be of the same state (gas, liquid, or solid)

Learning Goal 2: Describe how chemical reactions are affected by reaction conditions. 4- What is measured by the heat of reaction? 5- What is meant by the rate of a chemical reaction? 6- Mention the three conditions required for a chemical reaction to occur according to Collision Theory. 7- Describe factors that affect the rate of a reaction according to the Collision Theory (temperature, concentrations of reactants, catalyst, and reactant surface)

Why does increasing the temperature increase the rate of reaction? I. The frequency of collisions increases, therefore increasing the probability of reaction. II. Every collision will occur with the correct orientation, therefore increasing the probability of reaction. III. The activation energy is lower, therefore more reactant molecules have enough energy to get over the activation energy barrier. IV. The energy of collisions increases, therefore more of the collisions transfer enough energy to get over the activation energy barrier.
