Question

Decomposition of A is a first order reaction at T(K) and is given by A(g) B(g) + C(g). In a closed 1 L vessel, 1 bar A(g) is allowed to decompose at T(K). After 100 minutes, the total pressure was 1.5 bar. What is the rate constant (in min –1) of the reaction ? (log 2 = 0.3) (A) 6.9 × 10 –1 (B) 6.9 × 10 –3 (C) 6.9 × 10 –2 (D) 6.9 × 10 –4
