Given,
For every 10 ∘C rise of temperature, the rate is doubled. Thus, the temperature coefficient of the reaction = 2
Let, the initial rate = r1
New rate r2=r1×2(Temperature difference/10)
Temperature is increased by 50 ∘C
Hence, rate increases by
r2=r1×2(50/10)=25r1
Hence, the rate is increased by 32 times.
