Question

The kinetics of the following second-order reaction were studied as a function of temperature:
C2H5Br(aq)+OH−(aq)→C2H5OH(l)+Br−(aq)

Temperature (∘C)	k (L/mol⋠s)
25	8.81×10−5
35	0.000285
45	0.000854
55	0.00239
65	0.00633

Part A: Determine the activation energy for the reaction.

Part B: Determine the frequency factor for the reaction.

Part C: Determine the rate constant at 10 ∘C.

Express your answer using two significant figures.

Part D: If a reaction mixture is 0.145 M in C2H5Br, and 0.250 M in OH−, what is the initial rate of the reaction at 90 ∘C?

Express your answer using two significant figures.
