zs. Which line Cand D to form energy for the reaction between A and B (D) 3-4 (B) 2-3 (A) 1-4 2s. The decomposition of hydrogen peroxide in the presence of iodide ion is believed to occur via dis lathis mechanism, fagmis (B) a is the overall reactian reactant (A) catalyst. (D) a product of the overall tractia the activated complex, unately describes the behavior af a catalyst? statement most accu A caulow the a reaction and hence the forward ncreases AG of produce Her mKtion and hence

Explanation / Answer

28)

The question is asking to consider reverse reaction

C+D ---> A+B

In the reverse reaction, activation energy = energy difference between energy of C+D and energy of 4

So it is line segment 3 --> 4

29)

It is asking the role of I- in the reaction

I- is looks to be consumed in the first step and regenerated in the second step

It is a catalyst

Catalyst is the one which appears to be consumed in the first step and regenerated in the final step of the reaction

So answer is A)
