Question

What factors affect the equilibrium constant?

Answer 1

In order to answer this problem we should first know about equilibrium. Chemical equilibrium is the condition of a chemical reaction in which all reactants and products are present in quantities that have no further ability to change over time, resulting in no detectable change in the system's properties.

Complete answer:
The equilibrium constant can be defined as the ratio between the amount of reactant and the amount of product used to determine chemical behaviour in a chemical reaction.
At equilibrium, Rate of forward Reaction = Rate of Backward Reaction.
The equilibrium is influenced by a number of factors.
-Change in concentration of any product or reactant.
The reaction, which is in the direction that replenishes the material that is extracted, releases the concentration of reactants or products removed. The composition of the mixture in chemical equilibrium changes when the concentration of the reactant or product is changed.
-Change in the pressure of the system.
The volume changes, which causes a shift in strain. Since the total number of gaseous reactants and products is now different, a change in pressure will turn the gaseous reaction.
-Change in temperature of the system.
The equilibrium constant is influenced by temperature changes, and the rate of reaction is also affected by temperature changes. The equilibrium constant of an exothermic reaction decreases as temperature rises.
The equilibrium constant in an endothermic reaction increases as the temperature rises.

Note:
An equilibrium stage is defined as the point where the rate of forward reaction equals the rate of backward reaction. The number of reactant molecules converting to products and product molecules converting to reactants is the same at this stage. Chemical equilibrium is dynamic since the same equilibrium can be achieved with the same reactants in identical conditions anywhere with continuous molecule exchange.
