In the start of summer, a given sample of milk turns sour at room temperature `(27^(@)C)` in `48` hours. In a refrigerator at `2^(@)C`, milk can be stored there times longer before it sours. Calculate the rate constant at `310 K`, when rate constant at `300 K` is `1.6 xx 10^(5)`A. `2.363 xx 10^(5)`B. `2.4 xx 10^(5)`C. `2.450 xx 10^(5)`D. `3.123 xx 10^(5)`

Answer» Correct Answer - A
`(k_(310))/(k_(300)) = 1.477`
`:. k_(310) = 1.477 xx k_(300) = 1.477 xx 1.6 xx 10^(5)`
`= 2.363 xx 10^(5)`
