and I
2
, at 508°C has a half-life of 135 minutes when P
Hl
= 0.1 atm (initially), which comes down to one tenth of that value when the initial pressure is 1 atm. Calculate the rate constant.
(b) In a kinetic study of the reduction of nitric oxide with hydrogen, the initial pressure of 340 mm, an equimolar mixture of gases was reduced to half the value in 102 seconds. In another experiment, the initial pressure of 288 mm, under the same conditions was reduced to half the value in 140 sec. Calculate the order of the reaction.
