The rate would double b. 33. order with respect to reactant A. What would be the effect on the rate if the The rate would quadruple c. The rate would decrease by half d. e· The rate would increase in an unpredictable way The concentration of A has no effect on the rateExplanation / Answer
27. Letter C reprsents enthalpy change of the reaction.
28. Letter A represents activation energy of the forward reaction.
29. Letter D represents location of activated complex.
30. This is an endothermic reaction as product has more energy than reactant.
31. a. 0.22 mole/L.s
32. Option c
33.Option B
