The rate of decomposition of a gaseous acetaldehy

Question

The rate of decomposition of a gaseous acetaldehyde (CH³CHO) to gaseous methane and carbon monoxide is found to increase by a factor of 283,When the initial concentration of acetaldehyde is doubled. What is the order of this reaction?

Arun · Accepted Answer

As we learned nth order reaction - The rates of the reaction is proportional to nth power of reactant - wherein Differential rate law =\frac{dx}{dt}=k(a-x)^{n} Integrated rate laws, =\frac{1}{n-1}[(a-x)^{1-n} -a^{(1-n)}]=k_nt a= initial, concentration of reactant at t=0 sec x= concentration of product formed at t= tsec t_\frac{1}{2}=\frac{1}{(n-1)(a^{n-1})(k_n)}[2^{n-1}-1] Formulae for all the order except n=1Let rate law be: r=K\left [ acetaldehyde \right ]^{n} \therefore 1= K\left ( 0.95\: P_{o} \right )^{n} 0.5=K\left ( 0.67\: P_{o})^{n} \right So\: 2= \left ( \frac{0.95}{0.67} \right )\Rightarrow 2= \left ( 1.41 \right )^{n}\therefore n;2
