The pressure of a gas decomposing at the surface of a solid catalyst has been measured at different times and the results are given below:

t/s

0

100

200

300

p/pascal

4.0 x 10³

3.5 x 10³

3.0 x 10³

2.5 x 10³

Determine the order of reaction, its rate constant and half-life period.

Answer

The rate of reaction between different time interval
is

As rate remains constant, therefore, reaction is of zero order.
