The reaction 2NO2(g)2NO(g)+O2(g) is suspected to be second order in NO2. Which of the following kinetic plots would be the most useful to confirm whether or not the reaction is second order? A) A plot of [NO2]1 vs. t B) A plot of ln[NO2] vs. t C) A plot of [NO2] vs.t D) A plot of [NO2]2 vs.t Question 6 (2 points) For the chemical reaction AB+C, a plot of [A]t versus time is found to give a straight line with a negative slope. What is the order of reaction with respect to A ? A) zero B) first C) second D) Such a plot cannot reveal the order of the reaction
