The decomposition reaction 
is started in a closed cylinder under isothermal isochoric condition at an initial pressure of 1 atm. After Y x 10 3 s, the pressure inside the cylinder is found to be 1.45 atm. If the rate constant of the reaction is 5 x 10 -4 s -1 , assuming ideal gas behaviour, the value of Y is_______
Text Solution
Verified by ExpertsThe correct answer is:
2.30
(2.30)
Unit of K represent it is first order reaction.
2N 2 O 5 
2N 2 O 4 +O 2
t=0 1 0 0
t = t 1-P P P/2
1-P + P + 
= 1.45
Y=2.30
