Which of the following statements is correct about the equilibrium constant?
Which of the following statements is correct about the equilibrium constant?
- A. Its value increases by increase in temperature
- B. Its value decreases by decrease in temperature
- C. Its value may increase or decrease with increase in temperature
- D. Its value is constant at all temperature
Step-by-step solution
The equilibrium constant depends on temperature according to the van't Hoff equation. For exothermic reactions, increasing temperature decreases K; for endothermic reactions, increasing temperature increases K. Hence K may increase or decrease with temperature.
