A. 34.2<\/p>\n

B. 58.8<\/p>\n

C. 53.6<\/p>\n

D. 100.8<\/p>\n

Answer:-\u00a0<\/strong>Correct option is C)\u00a053.6<\/p>\n

We are specified that:<\/p>\n

When T1\u200b=27+273=300K<\/p>\n

Let k1\u200b=k<\/p>\n

When T2\u200b=37+273=310K<\/p>\n

k2\u200b=2k<\/p>\n

Substituting these values, the equation:<\/p>\n

log(k1\u200bk2\u200b\u200b) =2.303Ea\u200b\u200b\u00d7(T1\u200bT2\u200bT2\u200b\u2013T1\u200b\u200b)<\/p>\n

We will get:<\/p>\n

log(k2k\u200b) =2.303\u00d78.314Ea\u200b\u200b (300\u00d7310310\u2212300\u200b)<\/p>\n

log (2) =2.303\u00d78.314Ea\u200b\u200b (300\u00d731010\u200b)<\/p>\n

Ea\u200b=53598.6\u00a0Jmol\u22121<\/p>\n

Ea\u200b=53.6\u00a0kJmol\u22121<\/p>\n

Henceforth, the energy of activation of the reaction is 53.6\u00a0kJmol\u22121<\/p>\n","protected":false},"excerpt":{"rendered":"
