At 518^(@) 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% has reacted and 0.5 torr s^(-1) when 33% had reacted.The order of the reaction is :

Answer»

2
3
1
0

Solution :`(r_(1))/(r_(2))=((95)/(67))^(X)therefore 2=((95)/(67))^(x)`
`therefore` x log `((95)/(67))=2`
`thererfore` x=second ORDER
