Reactant formation in an endothermic reaction would be favored by which of the following?
- A
Increase in temperature
- B
Decrease in temperature
- C
No change in temperature
- D
First increase and then decrease in temperature
Increasing the temperature of the system provides more heat energy to the reaction, which helps drive the reaction toward the reactant side.
Increasing the temperature of the system provides more heat energy to the reaction, which helps drive the reaction toward the reactant side.
Decreasing the temperature would have the opposite effect. It would reduce the availability of heat energy for the reaction, making it less favorable for reactant formation.
Keeping the temperature constant would not provide any additional heat energy to favor reactant formation in an endothermic reaction.
This option is also incorrect. This pattern of temperature change would depend on the specific reaction and its temperature dependence. However, the initial increase in temperature would favor the formation of reactants in an endothermic reaction.
