In a proposed reaction mechanism, the rate-determining step involves the collision of two reactant molecules: NO and O2. What is the molecularity of the rate-determining step?

A mechanism for a naturally occurring reaction that destroys ozone is given by the following steps:Step 1: O3(g) + HO(g) → HO2(g) + O2(g)Step 2: HO2(g) + O(g) → HO(g) + O2(g)What is the molecularity of the overall reaction?

Consider the following three-step mechanism for a reaction: Step 1: Cl2(g) ⇌ 2Cl(g) (fast) Step 2: Cl(g) + CHCl3(g) → HCl(g) + CCl3(g) (slow) Step 3: Cl(g) + CCl3(g) → CCl4(g) (fast). Which species are intermediates in this mechanism?

An elementary reaction is known to be bimolecular. What does this mean?

Given the following three elementary steps:1) NO_2 + CO → NO + CO_22) NO_2 + NO → NO_3 + NO3) NO_3 + CO → NO_2 + CO_2What is the overall reaction that results from these steps?
