As noted in 2 above k values are generally needed along with t's in order to find ea. Describe briefly how the student can use the measured reaction time t for each trial to get Ea.
a) By plotting ln(t) vs. 1/T and finding the slope
b) By plotting ln(t) vs. T and finding the y-intercept
c) By dividing the change in temperature by the change in time
d) By multiplying the rate constant (k) by the temperature (T)
