Kinetics relationships and applicable constants are on the reverse side. I. For the reaction A + 2 B + C barb2right D + 2 E the following initial rate data were collected at 298 K, with concentrations in mol/L: Trial [A] [B] [C] Rate (M·s-1 ) 1 0.024 0.085 0.032 6.0 x 10-6 2 0.072 0.085 0.032 2.0 x 10-6 3 0.024 0.034 0.080 1.5 x 10-5 4 0.012 0.170 0.032 1.5 x 10-6 What is the order with respect to A only ? (3 points) II. For the reaction HO(g) + H 2 (g) barb2right H 2 O(g) + H(g), a plot of (ln k ) versus (1/T) yields a straight line and an activation energy of 42,000 J/mol. Calculate the slope of this linear graph. (2 points) III.
