Question

Two reaction proceed at 25c at same rate the temp coeffocient of the first reaction is 2 and that of second os 2.5 find ratio of rates of second reax to first reaction at 95c

Answer 1

The ratio of rates of second reaction to first reaction at 95°C is 4/5.

Step-by-step explanation:

• After every 10°C rise in temperature the the coefficient factors of a reaction also increase respectively.
• Both reactions have same rate constants at 25°C.
• At 95°C, for the reaction with rate whose temperature coefficient 2 is

K  95  =K  25  (  95−25 / 10 )×2= 14 K  25

And for the another reaction

K  ′95  =K  25  (  95−25 / 10 )×2.5 = 17.5 K 25

Hence, the ratio is

14 K 25 / 17.5 K = 28 / 35 = 4/5
