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.

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?

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
