Consider the reaction between 2-bromopropane and hydroxide ion (OH-) in a solvent with a dielectric constant of 80. Calculate the rate constant for the reaction at a temperature of 25°C using the Eyring equation. Assume the activation energy for the reaction is 40 kJ/mol and the pre-exponential factor is 10^12 s^-1.

Part B: Given the rate constant calculated in Part A, what is the half-life of the reaction at a concentration of 0.1 M?

Part C: If the reaction in Part A were to take place in a solvent with a dielectric constant of 20, would the rate constant increase or decrease? Explain your answer?
