(17 points) - Consider the following gas-phase decomposition reaction and rate law. AzBg) 2A(g) + B(g) What order is this reaction with respect to A₂B? If [A] is increasing at 0.58 mol/L's, how fast is [A B] decreasing? => rate = k[A₂B]² If k = 0.70 L/mol's, how long will it take for [AB] to reach 1/3 of its initial concentration of 1.50 M? If the initial concentration of AB ([AB]) is 1.50 M, what is the concentration at t = 12.3 s? (k = 0.7 L/mol's) Below is a plot of the reaction coordinate for this reaction. Draw how you would expect the plot to change if a catalyst was added to this reaction: Energy Reaction Progress
