Question

For an endothermic reaction, how will the value for Keq change when the temperature is increased?

A Keq is not effected by temperature.
B Keq will decrease.
C Keq will increase.
D It will be reduced by half.
PLATO

Answer 1

I put the answer C: Keq will increase, on PLATO. Hope this works for you!

Answer 2

C. Keq will increase

Step-by-step explanation:

Endothermic means the reaction will absorb heat to occur, hence an increase in temperature will favor the reaction, increasing the formation of products.

Keq is the equilibrium constant of the reaction, and it can be defined as:

`Keq = (concentration of products)/(concentration of reactants)`

In an endothermic reaction the equilibrium will be shift towards the formation of products when the temperature is increased, the concentration of products will increase (in relation to the concentration of reactants) ; so as a result the equilibrium constant Keq will also increase.
