On increasing the temperature by $10^{0}$C:
AnswerClick to flip back
A
number of fruitful collisions gets doubled
💡 Explanation:
Increasing the temperature of the substance, increases the fraction of molecules which collide with energies greater than $Ea$. For every $10^0 C$ rise in temperature, the fraction of molecules having energy equal to or greater than Ea gets doubled leading to doubling the rate of reaction.
Hence, the number of fruitful collisions gets doubled.
