QUESTION :

Given reaction is catalyzed by carbonic anhydrase CO + H2O —> H2CO3. If the temperature of the reaction increase i-e during exercise then how will the rate of reaction change?

  • increases
  • decreases
  • constant
  • none

ANSWER: A

EXPLANATION:

Increase temp directly increase the relative velocity of each reactant that will increase the chance of collision of reactants and form product with the help of carbonic anhydrase. This can be shown in the following equation ……. k=Ae^-E/RT = A/ e^ -E/RT ………… An increase in Temperature will Decrease the denominator. This is because e^ E/RT becomes e^o = 1 The overall effect is an increase in reaction rate. PRESS THE RED BELL TO GET EVERY DAY MCAT AND MDCAT QUESTIONS OF ALL SUBJECTS
