Interpretation Introduction
Interpretation:
The true statement has to be identified from the given set of statements.
Concept introduction:
Rate constant: Rate law is the equation that relates the concentration of the reactant to the rate of the reaction. Consider the reaction where the reactant
A and
B is giving product
P.
A+B→P
The rate law of the reaction can be expressed as given below.
Rate∞[A][B]orRate=k[A][B]
The proportionality sign is changed by a constant
k, which is the rate constant of the reaction. Rate constant depends upon the temperature, pressure and activation energy.
Half- life(t12): It is the time taken to reduce the concentration of the reactant to half of its initial value. Half-life of a second order reaction is calculated using the equation given below.
t12=1k[AB]°
Where,
k is the rate constant of the reaction.
[AB]° is the initial concentration of the reactant.
