The slope in the plot of [R] vs. time for a zero order reaction is
The rate of reaction is concerned with decrease in concentration of reactants or increase in the concentration of products per unit time. It can be expressed as instantaneous rate at a particular instant of time and average rate over a large interval of time. Mathematical representation of rate of reaction is given by rate law. Rate constant and order of a reaction can be determined from rate law or its integrated rate equation.
For a reaction P + 2Q → Products Rate = k[P]1/2[Q]1. What is the order of the reaction?
Define pseudo first order reaction with an example.
A first order reaction takes 40 min for 30% decomposition. Calculate t1/2.
Define rate constant.
A reaction is first order in A and second order in B.
Write the differential rate equation.
How is the rate affected on increasing the concentration of B three times?
How is the rate affected when the concentrations of both A and B are doubled?
Define half-life of a reaction.
Write the expression of half-life for zero order reaction.
Write the expression of half-life for first order reaction.
Explain the difference between the instantaneous rate of a reaction and the average rate of a reaction.
Compare the average rate and instantaneous rate of a reaction.
The rate constant for a first order reaction is 60 s-1. How much time will it take to reduce the initial concentration of the reactant to its th value?
Write two factors that affect the rate of a chemical reaction.
Write two conditions for the collisions to be effective collisions.
A first order reaction is 50% completed in 40 minutes at 300 K and in 20 minutes at 320 K. (Given: log 2 = 0.3010, log 4 = 0.6021, R = 8.314 JK-1mol-1)
Calculate the activation energy of the reaction.
A first order reaction is 20% completed in 5 min. Calculate the time taken for the reaction to be 60% complete.
