JEE Chemistry - MCQ Practice Questions

The decomposition of N₂O₅ is a first-order reaction. If 50% decomposes in 30 minutes, what is the rate constant?

In the reaction A → Products, doubling [A] increases rate by 4 times. The order of reaction is:

For an elementary reaction: 2A + B → Products, the rate law is:

Which statement about potential energy diagrams is CORRECT?

The integrated rate law for second-order reaction is 1/[A] = 1/[A]₀ + kt. If [A]₀ = 0.5 M, k = 0.4 M⁻¹s⁻¹, find [A] after 5 seconds

The half-life of a second-order reaction is 100 s when initial concentration is 0.5 M. What is the rate constant?
