Question
A chemical reaction was carried out at 300 K and 280 K. The rate constants were found to be K1 and K2 respectively then
Answer: Option B
:
B
Let the rate constant at 300 K be K1. Temperature decrease of 10∘C, rate constant value becomes approximately half the original value.
Decrease in temperature = 20∘C
The rate constant, K2 at 280 C is K2=0.25K1
K2=0.25K1
