Catalytic decomposition of nitrous oxide by gold at 900∘C at an initial pressure of 200 mm was 50% in 53 minute and 73% in 100 minute. (Roorkhee 1990)
(1) What is the order of reaction?
(2) Calculate velocity constant.
(3) How much will it decompose in 100 minute at the same temperature but at an initial pressure of 600 mm?
