Question

A(g) 2B(g) + C(g) For the given reaction, if the initial pressure is 450 mm Hg and the pressure at time t is 720 mm Hg at a constant temperature T and constant volume V. The fraction of A(g) decomposed under these conditions is x × 10–1. The value of x is (nearest integer)

Correct answer: .. A(g) 2B(g) + C(g) t = 0 0 t = t 450-x 2x x 720 = 450 – x + 2x + x or x = 135 135 = 0.3 = 3 x 10–1
