Answer 1

Answer;

Large

If a reaction is exothermic and produces large quantities of heat reaching equilibrium, its equilibrium constant will be large.

Explanation;

• Chemical equations may either be exothermic or endothermic based on the energy changes in the reaction. Exothermic reactions are those reactions that loose heat energy to the surrounding, therefore the enthalpy change in these reactions is negative. Endothermic reaction on the other hand are those reactions in which energy is absorbed from the reaction thus their enthalpy is positive.
• Chemical equilibrium in chemical reactions occurs when the rate of forward reaction is equal to the rate of reverse reaction. Equilibrium constant is the value of the chemical reaction quotient when the equilibrium of a reaction is achieved.
• If a reaction is exothermic and produces large quantities of heat in order to reach equilibrium then the equilibrium constant will be large.

Answer 2

The equilibrium constant will be lowered and the equilibrium will shift to the left if the heat being produced is not removed.
