For a first order reaction, the ratio of the time for 75 % completion of a reaction to the time for 50 % completion is ___________ . (Integer answer)

Correct answer

0

Step-by-step solution

T = 2 . 303 k log 100 100 - x % T 75 % = 2 . 303 k log 100 25 T 50 % = 2 . 303 k log 100 50 T 75 %   T 50 % = log 4 log 2 = 2
