Question

58.
The kinetic data for the given reaction A(g).+ 2B(g)*C(g) is provided in the following table fo
experiments at 300 K.
Ex. No. (A/M] [B/M] Initial rate (M sec )
1. 0.01 0.01 6.930x10
2. | 0.02 0.01 1.386x10-5
0.02 0.02 1.386x10-5
In another experiment starting with initial concen
the rate of reaction after 50 minutes from start of experim
inent starting with initial concentration of 0.5 and 1 M respetively for A and B at 300 K, find
50 minutes from start of experiment (in M/sec).
. (b) 0.25x10 (c) 4.33*10- (d) 3.46x10-4
4
(b)
(a):6.93x10-4​

Answer 1

Answer:

From the given data we can see that, its a first order as its rate depends only conc of A and rate constant is

$6.93*10^{-4}$

so by first order reaction rate of reaction after 50 mm is $4.33*10^{-5}$
