onsider the reaction of ozone (0.) with nitrogen monoxide (NO), hich occurs in smog. What effect would each of the following changes ave on the rate of this reaction? O3(g) + NO(g) O2(g) + NO2(g) nereasing the concentration of O, ecreasing the concentration of NO ncreasing the temperature ecreasing the temperature
The oxidation of ammonia produces nitrogen and water via the reaction: 4NH3(g) + 302(g) ---> 2N2(g) + 6H₂O(g). If the rate of formation of nitrogen gas is 2.0 mol/(Los), then the rate at which: water is formed is also 2.0 mol/(Los) oxygen reacts is 1.5 mol/(Los) ammonia reacts is 0.5 mol/(L •s) ammonia reacts is 4.0 mol/(Los) water is being formed is 0.67 mol/(Los)
1. Which of the following conditions describe the two step reaction energy profile below? (choose all that apply) Ea PE - ΔΕ Reaction Coordinate The first step is the rate determining step The first step is exothermic The second step is the rate determining step The second step is exothermic The overall reaction is endothermic
The rate of a certain reaction is given by the following rate law: rate =k| N,| H2 -k[N;][H+]° Use this information to answer the questions below. What is the reaction order in N,? What is the reaction order in H2? What is overall reaction order? At a certain concentration of N, and H2, the initial rate of reaction is 0.620 M / s. What would the initial rate of the reaction be if the concentration of N, were halved? Round M S your answer to 3 significant digits. The rate of the reaction is measured to be 24.0 M / s when [N2] = 1.5 M and [H2] = 0.16 M. Calculate the value of the k = |M -2 -1 •S rate constant. Round your answer to 2 significant digits.
Burning methane with oxygen is a highly exothermic reaction. Yet a mixture of methane and oxygen can be kept indefinitely without any reaction occurring. How is this possible?
