Dependence of Rate on Concentration, Rate Expression and Rate Constant, Order of a Reaction, Molecularity of a Reaction
For a reaction R ---> P, half-life (t1/2) is observed to be independent of the initial concentration of reactants. What is the order of reaction?
For a reaction A + B ⟶ P, the rate is given by
Rate = k [A] [B]2
How is the rate of reaction affected if the concentration of B is doubled?
The following results have been obtained during the kinetic studies of the reaction:
2A + B → C + D
|Experiment||A/ mol L−1||B/ mol L−1||Initial rate of formation of D/mol L−1 min−1|
|I||0.1||0.1||6.0 × 10−3|
|II||0.3||0.2||7.2 × 10−2|
|III||0.3||0.4||2.40 × 10−2|
Determine the rate law and the rate constant for the reaction.
Time required to decompose SO2Cl2 to half of its initial amount is 60 minutes. If the decomposition is a first order reaction, calculate the rate constant of the reaction.
A first order reaction has a rate constant 1.15 10−3 s−1. How long will 5 g of this reactant take to reduce to 3 g?
