I kept on getting 1.13s^-1 as my value for k2 but it's wrong...

**Chemistry**

Given that the initial rate constant is 0.0190s^-1 at an initial temperature of 20 degrees Celsius, what would the rate constant be at a temperature of 170 degrees Celsius? Activation energy = 45.2kJ/mol

**Chemistry**

The rate constant for a certain reaction is k=8.90×10^−3 s^-1. If the initial reactant concentration was 0.400M, what will the concentration be after 13.0 minutes?
