The frequency factor, A, can be determined from the Arrhenius equation:k = A * exp(-Ea/RT)where k is the rate constant, A is the frequency factor, Ea is the activation energy, R is the gas constant, and T is the temperature.Taking the natural logarithm of both sides of the equation, we get:ln(k) = ln(A) - Ea/RTPlotting ln(k) versus 1/T should give a straight line with a slope of -Ea/R and an intercept of ln(A).From the given data, we can calculate the values of ln(k) and 1/T:ln(k)	1/T-4	0.000252	0.0004-3	0.0001472	0.00025Plotting these values gives a straight line with a slope of -10000 and an intercept of 0.85.Therefore, the frequency factor, A, is e^0.85 = 2.3.
