The reaction (CH_3)3CBr + OH- rightarrow (CH_3)_3COH + Br- In a certain solvent

Question

The reaction (CH_3)3CBr + OH- rightarrow (CH_3)_3COH + Br- In a certain solvent Is first order with respect to (CH_3)_3CBr and zero order with respect to OH- In several experiments, the rate constant k was determined at different temperatures. A plot of In(k) versus 1/T was constructed that resulted In a straight line with a slope value of -1.10 time 10^4 K and a y-intercept of Assume that k has units of s-1. Determine the activation energy for this reaction. kJ/mol Determine the value of the frequency factor A. S_1 Calculate the value of k at 22degreeC. times -1

Explanation / Answer

ln k = ln A - (Ea / R) T

here slope m = - (Ea / R)

b)

y-intercept = ln A = 33.2

ln A = 33.2

A = 2.62 x 10^14

frequency factor A = 2.62 x 10^14

c)

ln k = ln A - Ea/R T

= ln (2.62 x 10^14) - 91.7 / 8.314 x 10^-3 x T

here to calculate k value we know T (temperature).
