Average Rate 4 The compound AX 2 decomposes according to the equation, 2 AX 2 (g) => 2 AX(g) + X 2 (g). In one experiment, [AX 2 ] was measured at various times, and these data recorded: Time (s) [AX 2 ] mol/L 00 . 0 5 0 0 2.0 0.0448 6.0 0.0300 8.0 0.0249 10.0 0.0209 20.0 0.0088 What is the average rate from 2.0 to 6.0 seconds in mol / L s? Use 3 significant figures. [don't include units in your answer; if you want to use scientific notation, use the E format. e.g., 0.0011 is 1.1E-3 Student Response Value Correct Answer 1. 3.7E-3 100% Equals 0.0037 (0%) Equals 3.7E-3 (100%) Contains .0037 (100%) Equals 3.70E-3 (100%) Score: 1/1 2. Relative Rates of Substances 17 Consider the reaction, 2 D(g) + 3 E(g) + F(g) => 2 G(g) + H(g) When [H] is increasing at 0.47 mol/Ls, how quickly is [D] decreasing? Student Response Value Correct Answer Answer .94 100% 0.940 Score: 1/1 3. Rate Law General 6 What is the overall reaction order for Cl 2 in a reaction with the following rate law?
