Question

The rate constant, the activation energy and arrhenius parameter of a chemical reaction at 25c are x, 10x and 2x.Value of rate constant state t at infinity is

Answer 1

Answer:

Correct option is

B

6.0×10

14

s

−1

Arrhenius equation

⇒K=Ae

−Ea/RT

As T→∞,

RT→∞

RT

−Ea

→0

e

−Ea/RT

→1

Hence K→A as T→∞

∴Value of K as T→∞ = 6.0×10

14

S

−1
