When the chemical reaction doubles in rate for each 10° temperature increase, the rate when increased to 40°C will be 16.
Note that for every 10° temperature, the rate is said to doubles (2)
and for 40°C, the double rate will be multiplied. So it will be:
2 x 2 x 2 x 2 = 16
Why does the rate of reaction increases?
A catalyst is known to be a factor that increases the rate of concentration of a reactant in any given solution.
It is known to be the one that boast the the surface area of a solid reactant, and so still increases the temperature as well as the rate of a reaction.
Therefore, the rate as at 40°C temperature will be 16 from the solution given above.
