Using the Arrhenius equation, k = Aexp(-Ea/RT), we can plot the natural logarithm of k against 1/T (in Kelvin) to get a straight line with a slope of -Ea/R and a y-intercept of ln(A). Then, we can use the given values to calculate ln(k) at both temperatures, and use linear regression to find the slope and y-intercept. The resulting equation is ln(k) = -1503.5/T + 12.662, where the slope corresponds to -Ea/R. Therefore, Ea/R = 1503.5 K, and solving for A gives A = k/T(-Ea/R) = 0.750 s^-1.
