Chemistry Question on coordination compounds
Two different first order reactions have rate constants k1 and k2 at T1(k1>k2). If temperature is increased from T1 to T2, then new constants become k3 and k4 respectively. Which among the following relations is correct?
A
(A) k1>k2=k3=k4
B
(B) k1<k3 and k2<k4
C
(C) k1=k3=k4
D
(D) k1>k2>k3>k4
Answer
(B) k1<k3 and k2<k4
Explanation
Solution
Explanation:
As given, the temperature is increased from T1 to T2, then new constants become k3 and k4 respectively.Rate constant increases with increase in temperature.So, k1<k3 and k2<k4Hence, the correct option is (B).
