At 5188o C, the rate of decomposition of a sample of gaseous acetaldehyde, initially at a pressure of 363 Torr, was 1.00 Torr s−1 when 5% had reacted and 0.5 Torr s−1 when 33% had reacted. The order of the reaction is :
0
2
3
1
As we learned
nth order reaction -
The rates of the reaction is proportional to nth power of reactant
- wherein
Differential rate law
Integrated rate laws,
a= initial, concentration of reactant at t=0 sec
x= concentration of product formed at t= tsec
Formulae for all the order except n=1
