A liquid decomposes by irreversible first order kinetics and the half life period of this reaction is 8 minutes. The time required for 75% conversion of the liquid will be ____________________ minutes?

Question

Accepted Answer

16. For first-order kinetics, the time for 75% conversion is calculated using the formula t = -0.693 * ln(1 - fraction converted) / k. Since t_half = 8 min, k = 0.693/8. Plugging in gives approximately 16 minutes.
