Question

Gaseous cyclobutene isomerizes to butadiene in a first order process which has a 'k ' value of 3.3 10^-4s^-1 at 153^ C. The time in minutes it takes for the isomerization to proceed 40 \% to completion at this temperature is _______(Rounded off to the nearest integer)

Accepted Answer

Correct answer: 26. 26 JEE Main 2021 For first order Rxn :t= 2.303k log ⁡ ( 100100-x ) X=40 ,k=3.3 10^-4 t= 2.3033.3 10^-4 log ⁡ ( 10060 ) For first order Rxn :t= 2 ,303k log ⁡ ( 100100-x ) X=40 ,k=3.3 10^-4 t= 2.3033.3 10^-4 log ⁡ ( 10060 ) t= 2.3033.3 10^-4 0.22 t=0.1535 .3 10^4 t=1535 sec t=0.1535 .3 10^4 t=1535 sec=25.6 Min

$Gaseous cyclobutene isomerizes to butadiene in a first order process which has a ’ k ’ value of 3.3 \times 10^{- 4} s^{- 1} at 153^{\circ} C . The time in minutes it takes for the isomerization to proceed 40 % to completion at this temperature is _______(Rounded off to the nearest integer)$
