The time taken in 75% completion of a zero-order reaction is 10 h. In what time, the reaction will b — Chemical Kinetics Chemistry Question

💡 Solution & Explanation

For a zero-order reaction: x = Kt. For 75% completion: 0.75 [A]0 = K * 10 => K / [A]0 = 0.075. For 90% completion: 0.90 [A]0 = K * t => t = 0.90 * ([A]0 / K) = 0.90 / 0.075 = 12.0 h.
