JEE Main & Advanced Chemistry Chemical Kinetics / रासायनिक बलगतिकी Sample Paper Topic Test - Chemical Kinetics

  • question_answer
    The following mechanism has been proposed for the exothermic catalyzed complex reaction
    If \[{{k}_{1}}\] is much smaller than \[{{k}_{2}},\] the most suitable qualitative plot of Potential Energy (PE) versus reaction coordinate (R.Co) for the above reaction.





    Correct Answer: B

    Solution :

    \[A+BlAB\] so \[{{E}_{a(f)}}\] its high and \[{{E}_{a(b)}}\] is low \[({{k}_{1}}<<{{k}_{2}});{{E}_{a}}\] for this step is very high and next step is low and overall reaction is exothermic.
