Which is correct about first-order reaction? — Chemical Kinetics Chemistry Question

💡 Solution & Explanation

For a first-order reaction, the time required for 75% completion (t_0.75) is related to the half-life (t_0.5) by the relation: t_0.75 = 2 × t_0.5. Given t_0.5 = 50 s, we have t_0.75 = 2 × 50 s = 100 s.
