Answer 1

TS #2 . Two transition stato - TS #1 & TS #2 EA, 1. IS # T obal b) One intemediate (I) - Reaction is exorgonic - Ep (product) < Er creactont) energy released. . d) Rate determining step is staw step K = A e-E/RT RT ka e sincs Eag> Ear k would be lovest for II (2nd) step. Hence rate- limiting step is second step. re 2= 1 b) reaction K [so2 trst order kineties 0.2% 2.24.10 4.
