NEET 2020Chemical Kinetics· Activation energy, effect of catalyst, and rate-determining stepmedium
Q4.A complex reaction proceeds via a two-step mechanism:
1. A + B → X (slow step, activation energy Ea₁ = 50 kJ/mol)
2. X + C → P (fast step, activation energy Ea₂ = 20 kJ/mol)
The overall reaction is A + B + C → P. If a catalyst is added that lowers the activation energy of the slow step by 10 kJ/mol, what will be the effect on the overall rate constant (k)?
