Nitrogen dioxide is formed from the reaction of nitrogen monoxide and oxygen gas.

2 NO (g) + O₂ (g) → 2 NO₂ (g)

Tabulated below is the initial rate of formation of NO₂ data.

Calculate the initial rate of formation of nitrogen dioxide when the initial concentrations are [NO] = 0.300 M and [O₂] = 0.450 M.   

In vessels 1, 2, and 3, of equal volumes, the reaction X + Y → XY has relative rates of 1:2:1. X molecules are represented by red spheres, and Y molecules are represented by gray spheres.

Determine the order of reaction in X and Y.

Imagine a reaction with reactants X, Y, and Z. The reaction is second order in X, first order in Y, and zero order in Z. The concentration of all of the reactants is doubled. Which of the following is true about the rate change?

At 500 K, the reaction 2 A + B → C has a rate constant of 4.8 × 10^–3 M^–2 s^–1. The reaction is first order in A and second order in B. What is the rate at 500 K if [A] = 0.250 M and [B] = 0.090 M?

For the hypothetical reaction,

WX + YZ → WXYZ

the following data was gathered:

Determine the overall order of the reaction.

Write the rate law for a reaction that is second order in A, zero order in B, and first order in C. Reaction: A + B + C → products

Use the graph below to determine the order of the reaction with respect to A.
