Given the following data, determine the rate constant (in M-2s-1) of the reaction 2NO(g) + Cl2(g) –→ 2NOCI(g) [Cl2] (M) Rate (M/s) 3.4 x 104 8.5 x 105 3.4 x 104 Experiment [NO] (M) 1 0.0300 0.0100 0.0150 0.0100 3 0.0150 0.0400 Note: Answers must be numeric, not alphanumeric-42, not forty-two.

(a) Select all of the correct statements about reaction rates from the choices below. The lower the rate of a reaction the longer it takes to reach completion. A balanced chemical reaction is necessary to relate the rate of reaction to the concentration of a reactant. As a reaction progresses its rate goes down. The rate of a slow step has more effect on the overall reaction rate than the rate of a fast step. Reaction rates are determined by reactant concentrations, temperatures, and reactant stabilities. Reaction rates increase with increasing temperature. Reactions involving very unstable combinations of chemicals have large rate constants.

The data below were collected for the following reaction: CH3CI(g) + 3 Cl2(g) CCI4(g) + 3 HCI(g) [CH3CI] / mol L-1 Initial Rate / mol L-1 s-1 Trial [Cl2] / mol L-1 1 0.050 0.050 0.0142 2 0.100 0.050 0.0290 3 0.200 0.200 0.115 What is the order of the reaction with respect to Cl2?

Using the data in the table, calculate the rate constant of Trial [A] (M) [B] (M) Rate (M/s) this reaction. 1 0.260 0.280 0.0119 A + B → C+ D 2 0.260 0.784 0.0933 3 0.312 0.280 0.0143 Units k = M-²s-1 M-'s-! M-s-!

Calculate the average rate of the reaction between 10 and 20 seconds.

Another common component of reaction mechanism is a catalyst. These are compounds that change the reaction mechanism and provide a pathway with a lower activation energy, and correspondingly faster reaction rate. They are a reactant in an early step in the mechanism and a product in a later step. They do not appear in the overall reaction but do appear in the rate law. 3. A reaction occurs by the following mechanism; Step 1 Ce4+ + Mn²+ →→ Ce³+ + Mn³+ Step 2 Ce4+ + Mn³+ → Ce³+ + Mn²+ Step 3 Tit+ Mn+→ Ti³+ + Mn²+ a. Write the overall reaction. b. Identify each of the components as a reactant, product, intermediate, or catalyst; Mn²+ Mn³+ Ce4+ Ce ³+ Mn4+ Tit Ti³+ C. Assuming that the catalyst is involved in the rate determining step, what is the rate law for this reaction? 4. Under certain conditions, the reaction: 2 NO + Cl₂ → 2 NOCI is found to be second order in NO and first order Cl₂. Given the following mechanism; Step 1 NO + Cl2 → NOCI₂ Step 2 NOCI₂ + NO 2 NOCI a.
