An increase in temperature will Group of answer choices decrease the rate of a reaction. decrease the activation energy for a reaction. increase the amount of collisions in the system. increase the number of elementary steps in the reaction. none of the above.
The rate of a reaction is how quickly the reaction goes to completion. If two reactions have the same amount of reactant, increasing the rate does not increase the amount of product produced, it simply reduces the time that it takes to make the product.

Question: Consider a hypothetical chemical reaction between compound A and compound B. The reaction is exothermic and yields compound C and compound D as products. The reaction mechanism involves multiple elementary steps. Based on this information, answer the following questions: Define the terms "exothermic reaction" and "endothermic reaction" and provide an example of each. Explain the concept of a reaction mechanism and why it is important in understanding chemical reactions. Outline the steps involved in determining the rate-determining step in a reaction mechanism. Describe how a catalyst affects the rate of a chemical reaction and provide an example of a catalyst commonly used in industrial processes. Given that the reaction between compound A and compound B is exothermic, suggest one possible reason why the reaction might still have a high activation energy.

Increasing the temperature of a reaction increases the speed at which the reaction occurs. Identify the statements that explain the correlation between the increase in temperature and the increase in reaction rate. More atom-atom stretching and bending within the molecules occurs at higher temperatures, which creates more reactive molecular configurations. Added heat decreases the activation energy of a reaction and has a similar effect as adding a catalyst. ✔ Molecules at higher temperatures have greater kinetic energy, which results in more frequent and higher energy collisions. An increased temperature improves the reaction pathway by decreasing the energy difference between reactants and products.
