Question

Two reactions, A &#8594; Products &#160;and &#160;B &#8594; Products , have rate constants K a and K b at temperature T and activation energies E a and E b respectively. If K a > K b and E a < E b and assuming that A for both the reactions is same then :

Quantrex Academy · Accepted Answer

Correct answer: D. None of these (I) As temperature Rises K a will increase K b will also increase since E a < E b K a >> K b (II) At lower temperature K a will fall K b will fall But as E a < E b K' a > K' b (II) As temperature rises very high K a and K b will try to close each other as they are exponential functions of temperature

Two reactions, A → Products  and  B → Products , have rate constants K a and K b at temperature T and activation energies E a and E b respectively. If K a > K b and E a < E b and assuming that A for both the reactions is same then :
