For each of the following pairs of reaction diagrams, identify which of the pair iscatalyzed:

Short Answer

Expert verified

(a) Reaction diagram (b) is a catalyzed reaction.

(b) Reaction diagram (b) is a catalyzed reaction.

Step by step solution

01

Definition of Catalyst

Catalysts are substances which increase the rate of the reaction without getting used up by themselves while decreasing the activation energy of the reaction.

  • A catalyst increases the rate of reaction.
  • Catalyst accelerates the rate of a reaction by decreasing the activation energy.
  • Catalyst is regenerated during the reaction.
02

(a) Reaction diagram (b) uses a catalyst

  • The two reaction diagrams depict the same reaction, one with a catalyst and another without a catalyst.
  • We can ignore the energy aspect of the diagram as the catalyst does not involve in affecting the energy of the reactant or product.
  • But we can notice a small change in the transition state, which is lower in diagram (b) than in diagram (a).

This indicates the presence of a catalyst in diagram (b).

03

(b) Reaction diagram (b) uses a catalyst 

  • The two reaction diagrams depict the same reaction, one with a catalyst and another without a catalyst.
  • We can notice a small change in the transition state, which is lower in diagram (b) than in diagram (a).

This indicates the presence of a catalyst in diagram (b).Thus, the reaction diagram (b) is catalyzed among both pairs of reaction diagrams (a) and (b).

Under certain conditions, the decomposition of ammonia on a metal surface gives the following data:

Determine the rate law, the rate constant, and the overall order for this reaction.

How much and in what direction will each of the following effect the rate of the reaction:

CO(g) + \({\bf{NO}}{}_{\bf{2}}\) (g)鉄� \({\bf{CO}}{}_{\bf{2}}\) (g) + NO(g) if the rate law for the reaction is rate =\({\bf{k(NO}}{}_{\bf{2}}{{\bf{)}}^{\bf{2}}}{\bf{a}}\)?

  1. Decreasing the pressure of \({\bf{NO}}{}_{\bf{2}}\) from 0.50 atm to 0.250 atm.
  2. Increasing the concentration of CO from 0.01 M to 0.03 M.

The annual production of \({\bf{HN}}{{\bf{O}}_{\bf{3}}}\) in 2013 was 60 million metric tons Most of that was prepared by the following sequence of reactions, each run in a separate reaction vessel.

\(\begin{align}\left( a \right){\bf{ }}4N{H_3}{\bf{ }}\left( g \right){\bf{ }} + {\bf{ }}5{O_2}{\bf{ }}(g) \to 4NO\left( g \right){\bf{ }} + {\bf{ }}6{H_2}O\left( g \right)\\\left( b \right){\bf{ }}2NO\left( g \right){\bf{ }} + {\bf{ }}{O_{2{\bf{ }}}}(g) \to 2N{O_{2{\bf{ }}}}\left( g \right)\\\left( c \right){\bf{ }}3N{O_2}{\bf{ }}\left( g \right){\bf{ }} + {\bf{ }}{H_2}O(l) \to 2HN{O_3}(aq) + NO(g)\end{align}\)

The first reaction is run by burning ammonia in air over a platinum catalyst. This reaction is fast. The reaction in equation (c) is also fast. The second reaction limits the rate at which nitric acid can be prepared from ammonia. If equation (b) is second order in NO and first order in \({{\bf{O}}_{\bf{2}}}\), what is the rate of formation of \({\bf{N}}{{\bf{O}}_{\bf{2}}}\) when the oxygen concentration is 0.50 M and the nitric oxide concentration is 0.75 M? The rate constant for the reaction is \({\bf{5}}{\bf{.8 \times 1}}{{\bf{0}}^{{\bf{ - 6}}}}{\bf{ L}}{{\bf{ }}^{\bf{2}}}{\bf{ mo}}{{\bf{l}}^{{\bf{ - 2}}}}{\bf{ s}}{{\bf{ }}^{{\bf{ - 1}}}}\).

The rate constant for the radioactive decay of 14C is \({\bf{1}}{\bf{.21 \times 1}}{{\bf{0}}^{{\bf{ - 4}}}}{\bf{ yea}}{{\bf{r}}^{{\bf{ - 1}}}}\). The products of the decay are nitrogen atoms and electrons (beta particles): \(\begin{aligned}{}_{\bf{6}}^{{\bf{14}}}{\bf{C}} \to _{\bf{6}}^{{\bf{14}}}{\bf{N + }}{{\bf{e}}^{\bf{ - }}}\\{\bf{rate = k(}}_{\bf{6}}^{{\bf{14}}}{\bf{C)}}\end{aligned}\).

What is the instantaneous rate of production of N atoms in a sample with a carbon-14 content of \({\bf{ 6}}{\bf{.5 \times 1}}{{\bf{0}}^{{\bf{ - 9 }}}}{\bf{M}}\)?

The element Co exists in two oxidation states, Co(II) and Co(III), and the ions form many complexes. The rate at which one of the complexes of Co(III) was reduced by Fe(II) in water was measured. Determine the activation energy of the reaction from the following data:
