Question

in first order reaction for every 10degree Celsius in temp the rate becomes 2.2 times. if temp is increased from 40 to 80 degree celsius rate of reaction will be​

Answer 1

If the temperature of a first order reaction is increased from 40°C to 80°C, it rate becomes 23.4256 (2.2⁴) times the initial rate.

• It is given that the rate of the reaction becomes 2.2 times its initial rate for every 10°C rise in the temperature of the reaction.
• The net rise in temperature (ΔT) = 80-40 = 40°C
• It can be concluded that the ratio of the final rate to the initial  rate will be equal to 2.2^(ΔT/10) = 2.2^(40/10) = 2.2⁴ = 23.4256
