After how many seconds will the concentration of the reactants in a first order reaction be halved, if the decay constant is 1.155 × 10–3 sec–1.
Half-life of a first order reaction is 4s and the initial concentration of the reactant is 0.12 M. The concentration of the reactant left after 16 s is
The plot of concentration of the reactant vs time for a reaction is a straight line with a negative slope. The reaction follows a rate equation
The reaction A → B follows first order kinetics. The time taken for 0.8 mole of A to produce 0.6 mole of B is 1 hour. What is the time taken for conversion of 0.9 mole of A to produce 0.675 mole of B?
Which of the following graphs represent relation between initial concentration of reactants and half-life for third order reaction?
A first order reaction is 50 % completed in 30 minutes at 27 ºC. Its rate constant is :
A substance 'A' decomposes by a first order reaction starting initially with [A] = 2.00 M and after 200 min, [A] becomes 0.15 M. For this reaction t1/2 is
