Question

The following data were obtained from the first order decomposition of 2 A g → B g + C ( S ) at a constant volume and at a particular temperature S No. Time Total pressure in Pascal 1 At the end of 10 min 300 2 After completion 200 The rate constant in min -1 is

Quantrex Academy · Accepted Answer

Correct answer: A. 0.0693

2 A → B + C t = 0 2 P 0 - After 10 min 2 P - 2x x - After completion 0 P - Given, P = 200 after the completion 2 P - x = 300 (at the end of 10 min) x = 100 k = 2.303 10 l o g 200 100 = 0.0693 m i n - 1
