Atomic chlorine reconstitution may also occur via the single step mechanism shown below. CIO (g) + O (g) = Cl (g) + O2 (g) Which of the following is true for the reaction? O If temperature is increased, the activation energy of the reaction decreases O Neither is true O If the activation energy of the reaction is decreased, extent increases O Both are true
Atomic chlorine elimination may occur via the single step mechanism shown below. CI (g) + O2 (g) ECIO (g) + 0 (9) Which of the following AG vs. T graphs corresponds to this reaction? O AG T Ο ΔG T AG
The following process may take place in three steps: 2 CIO (g) =2 Cl (g) + O2 (g) S1: 2 CIO (g) = CIOOCI (g) S2: CIOOCI (g) = CIOO (g) + Cl (g) S3: CIOO (g) + Cl (g) + O2 (g) The rate law for this process has been experimentally determined to be Rate = k[CIO]?. Based off this information, which of the following statements is TRUE? O The reaction is first order overall O The rate law...
10. A reaction is thought to occur via the on is thought to occur via the following steps. What is the overall chemical equation for the reaction? step 1 O3 + O2 +0 (slow) step 2 O3 + Cl → CIO + O2 step 3 CIO +0 →CI + O2
18-12. The reaction described by 2 NO,(g) → 2NO(g) +0,(g) is postulated to occur via the mechanism (1) NO,(g) + NO,(g) - NO(g) + NO,(g) (slow) (2) NO,(g) → NO(g) + 0,(g) (fast) The rate law for the reaction is rate of reaction = k[NO,]? Is this mechanism consistent with the observed rate law? Justify your answer.
