The quantitative effect of temperature on chemical equilibrium is given by the____________________?
Correct answer: B. Van't-Hoff equation
- A. Le-Chatelier's principle
- B. Van't-Hoff equation
- C. Arrhenius equation
- D. None of these
Explanation
The van’t Hoff equation gives the quantitative relation between the equilibrium constant and temperature, involving the reaction enthalpy. Le Chatelier’s principle predicts the direction of the shift, while the Arrhenius equation concerns reaction-rate constants.
