the rate of the reaction at `25^(@)C` `"3 mol L"^(-1)" min"^(-1)` . The temperature coefficient of a reaction is 2 andCalculate the rate at the temperature `75^(@)C`.

Text Solution

Verified by Experts

According to Arrhenius, for every `10^(@)C` rise in the temperature, the temperature `=75^(@)C-25^(@)C=50^(@)C`
`=5xx10^(@)C`
The increase in the rate of the reaction `=2^(5)=32` times
The rate of reaction `75^(@)C=3xx32`
`=94" mol L"^(-1)"min"^(-1)`.
