Question

17. By increasing the temperature at an equilibrium reaction:

a. the reaction will move towards the endothermic reaction

b. the reaction speed constant is reduced

c. the reaction is accelerated as the number of sites where the reaction can occur increases

d. the exothermic reaction is favored

Answer 1

By increasing the temperature at an equilibrium reaction: the reaction will move towards the endothermic reaction.

This can be explained by the facts of endothermic reactions. In the endothermic reaction processed by the accepting heat or energy and the rate of the reaction increases as the energy of a reaction medium increases as well as the temperature of the endothermic reaction increase.

At high-temperature, reaction speed constant can't be reduced as with increasing temperature the kinetic energy of the reactant molecule increase as well as reaction speed constant also increases.

The reaction is not accelerated as the number of sites where the reaction can occur does not change. As the number of sites is fixed for closed system it does not depends on temperature.

For an exothermic reaction, the increasing temperature is not favorable the reaction itself gives energy.
