The following data are for the decomposition of ammonium nitrite in aqueous solution

The following kinetic data are provided for a reaction between A and B:

SO₂Cl₂ → SO₂ + Cl₂ is a first order gas reaction with k = 2.2 × 10^–5 sec^–1 at 320^oC. The percentage of SO₂Cl₂ decomposed on heating for 90 minutes is

A substance ‘A’ decomposes in solution following the first order kinetics. Flask I contains 1 L of 1 M solution of A and flask II contains 100 ml of 0.6 M solution. After 8 hr, the concentration of A in flask I becomes 0.25 M. What will be time for concentration of A in flask II to become 0.3 M?

If a is the initial concentration and k is the rate constant of a zero order reaction, the time for the reaction to go to completion will be

The activation energy of a reaction is 58.3 kJ mol^-1. The ratio of the rate constants at 305 K and 300 K is about (R = 8.3 JK^-1 mol^-1)

The hydrolysis of ethyl acetate was carried out separately with 0.05 M HCl and 0.05 M H₂SO₄. The rate constants were found to be k₁ and k₂ respectively. Then

A certain reaction A + B → P is of first order with respect to each reactant. If [A]₀ =0.1 M, [B]₀ = 5.0 M and the second order rate constant k is 6 × 10^–3 M^–1s^–1the half-life of the reaction in seconds is

Consider the following statements: The rate law for the acid catalysed hydrolysis of an ester being given as Rate = k [H⁺] [ester] = k’ [ester]. If the acid concentration is doubled at constant ester concentration
1. the second order rate constant, k is doubled
2. the pseudo first order rate constant, k is doubled
3. the rate of the reaction is doubled.
Which of the above statements are correct?

2A + B → 3C for the reaction instant rate of reaction is...
