In what time (in min), the partial pressure of DTBP is 100 torr? — Chemical Kinetics Chemistry Question

💡 Solution & Explanation

The pressure drops from 800 to 100 torr, which represents 1/8th of the original amount. This is equivalent to 3 half-lives (800 -> 400 -> 200 -> 100). Time = 3 × 80 min = 240 min. Therefore, correct answer is D.
