Question

The reaction A(g) + 2B(g) → C(g) + D(g) is an elementary process. In an experiment, the initial partial pressure of A and B PA = 0.60 and PB = 0.80 atm. when PC = 0.2 atm, the rate of reaction relative to the initial rate is

Options

A.1/48
B.1/24
C.9/16
D.1/6

Solution

r1 = k[A][B]2 = k[0.6] [0.80]2
After reaction
       A    +    2B    →      C    +    D
0.06 - 0.2           0.8 - 0.4            0.2        0.2
0.4        0.4                 0.2        0.2
