Milk turns sour at `40^(@)C` three times as faster as at `0^(@)C`. The energy of oxygen which can be used to completely convert 2L of `"SO"_(2)` gas ?

A

4.694 kcal

B

2.6 kcal

C

66.6 kcal

D

3.2 kcal

Text Solution

Verified by Experts

The correct Answer is:
A
`log""(k_(2))/(k_(1))=(E_(a))/(2.303R)[(T_(2)-T_(1))/(T_(1)T_(2))]`
`:.log3=(E_(a))/(2.303xx2)[(313-273)/(313xx273)]`
`:.E_(a)=4694" cal"~~4.694" k cal"`
