NCERT Solutions class 12 Chemistry Chemical kinetics In text question In-text question
1. For the reaction
, the concentration of a reactant changes from 0.03 M to 0.02 M in 25 minutes. Calculate the average rate of reaction using units of time both in minutes and seconds.
2. In a reaction, 
Products, the concentration of A decreases from 
to 
in 10 minutes. Calculate the rate during this interval?
3. For a reaction,
’Product; the rate law is given by, 
. What is the order of the reaction?
4. The conversion of molecules X to Y follows second order kinetics. If concentration of X is increased to three times how will it affect the rate of formation of Y?
5. A first order reaction has a rate constant 
. How long will 5 g of this reactant take to reduce to 3 g?
6. Time required to decompose 
to half of its initial amount is 60 minutes. If the decomposition is a first order reaction, calculate the rate constant of the reaction.
7. What will be the effect of temperature on rate constant?
8. The rate of the chemical reaction doubles for an increase of 10 K in absolute temperature from 298 K. Calculate 
.
9. The activation energy for the reaction 
is 
at 581 K. Calculate the fraction of molecules of reactants having energy equal to or greater than activation energy?
