The rate constant of a first order reaction is doubled when the temper – InterviewSolution

1.	The rate constant of a first order reaction is doubled when the temperature is increased from 20^(@)C to 25^(@)C . How many times the rate constant will increase if the temperature is raised from 20 ^(@)Cto 40^(@)C
Answer» 4 8 16 32 Solution :`5^(@)C` rise CAUSES increase of 2 time . `20^(@)C` will cause `(2)^(4) = 16` TIMES .
