The equilibrium constant of the following isomerisation reaction at 400K and 298 K are 2.07 and 3.42 respectively.
cis-butene 
trans-butene
Which of the following is/are correct ?
I. The reaction is exothermic
II. The reaction is endothermic
III. At 400K 50% of cis-butene and 50% of trans-butene are present of equilibrium
IV. Both at 298K and 400K, k 1 =k –1
Text Solution
Verified by ExpertsThe correct answer is:
D
As on T increase, K eq is increasing, Reaction is exothermic.
