A kineticist collects a series of rate constants at different temperatures for the first-order decomposition reaction, She plots the data in the form of an an Arrhenius plot (ln k on the y axis; 1/T on the x axis) and fits the data to the equation of a line. The slope and intercept of the resulting line are -12,500 K and 33.02, respectively. What is the value of k at 303 K?
