(b) Changes in and pressure

(c) Changes in temperature

(d) Changes in concentration, temperature, and pressure

The question was posed to me in an internship interview.

This interesting question is from Equilibrium Concentration Relationship in portion Contact Equilibrium Separation Process of Food Processing Unit Operations

Answer 1

Right choice is (d) Changes in concentration, temperature, and pressure

The best I can explain: Changes in concentration, temperature, and pressure can affect the position of equilibrium of a reversible reaction. If the forward reaction is endothermic, then there is an increase in temperature that causes the system to shift toward the products.
