Question

With an increase in temperature by $10K$, the rate of reaction becomes double. How many times the rate of reaction will be, if the temperature is increased from $303K$ to $353K$ ?

• A. $4$
• B. $8$
• C. $16$
• D. $32$

Answer 1

The correct option is D $32$

With every increase in temperature by $10K$, the rate of reaction becomes double, which means;

From $303-313K$, the rate becomes double, i.e., $2^1$.

From $313-323K$, the rate becomes $2^2$.

From $323-333K$, the rate becomes $2^3$.

From $333-343K$, the rate becomes $2^4$.

From $343-353K$, the rate becomes $2^5$.

Therefore, when the temperature increases from $303K$ to $353K$, the rate becomes $2^5=32times$.

Hence, option D is the correct answer.
