Question

Which of the following statements is true about the equilibrium constant and rate constant of a single-step chemical reaction?

• A. Equilibrium constant may increase or decrease, but rate constant always increases with temperature.
• B. Both equilibrium constant and rate constant increase with temperature
• C. Rate constant may increase or decrease, but equilibrium constant always increases with temperature.
• D. Both equilibrium constant and rate constant decrease with temperature

Answer 1

The Correct Option is A

• The Arrhenius equation describes the rate constant (k):
• The equilibrium constant (K) is determined by the reaction’s enthalpy change (\(\Delta H\)):
  Consequently, the equilibrium constant can either rise or fall based on the reaction type, whereas the rate constant invariably increases with temperature.
