JEE Advanced 2020 Full Test 7 Paper 2

Question : 25 of 54

Marks: +1, -0

Consider a parallel reaction,

Which of the following statement(s) is/are true?

When both the reactions are of 1‌st ‌ order, ‌
k1
k2
=‌
[X]
[Y]
‌
k1
k2
=‌
[X]
[Y]
is true for all parallel path reactions irrespective of their order.
The overall energy of activation is given by E=‌
k1E1+k2E2
E1+E2
, if the two parallel reactions are of same order.
For first order reaction, the plot of ln‌t1∕2 vs 1∕T is a straight line and slope of the line is equal to E\/R (where R is gas constant).
