Question

To cook a particular dish, the optimum temperature is ${70}^{o}C$. At ${50}^{o}C$ the dish will:

• A. get cooked slower
• B. get cooked faster
• C. not get cooked at all
• D. take twice the time to get cooked

Answer 1

Answer: (A)

get cooked slower

$K=A{e}^{-Ea/RT}$

The decrease in temperature will also decrease the value of the first-order rate constant.

$\therefore$ At ${50}^{0}C$ the dish will get cooked slower.
