Question

The rate constant of a reaction at 300K and 280K respectively are K1 and K2 then

A)K1=20K2
B)K2=4K1
C)K1=4K2
D)K1=0.5K2

Answer 1

Some data is missing in the question. "It is observed that for every 10degree Celsius rise in temperature rate constant is double."Thiss part is missing. So the answer would be
Let the rate at 290 be K

Then K = 2K2

and K1 = 2K

so K1 = 2*(2K2)

K1= 4K2

option C
