Which of the following statements is true about 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 & Solution
Correct Answer
(A) Equilibrium constant may increase or decrease but rate constant always increases with temperature
Step-by-step Solution
Detailed explanation
Hint : According to Van't Hoff equation \(\log \left(\frac{k_2}{k_1}\right)=\frac{\Delta H}{2.303 R}\left[\frac{1}{T_1}-\frac{1}{T_2}\right]\) Where \(\mathrm{k}_1\) and \(\mathrm{k}_2\) are Equilibrium Constants at \(\mathrm{T}_1\) and \(\mathrm{T}_2\) temperature respectively.…
