Chemical kinetics

The sum of the exponents to which the molar concentration in the rate law equation are raised is called

• Order of reaction

• Molecularity of reaction

• Speed of the reaction

• None of the above

The number of atoms /molecules/ions/reacts to form product in a elementary reaction is called

• Molecularity of the reaction

• Order of the reaction

• Speed of the reaction

• None of the above

Units of rate constant for first order reaction is

• Per second

• Per litre

• Per mol

• None of the above

For which order reaction units of rate constant and rate of reaction are same

• First order

• Zero order

• Second order

• None of the above

The reaction which takes place in a number of steps is

• Complex reaction

• Elementary reaction

• Neutral reaction

• All of the above

The reaction which takes place in a single step

• Elementary reaction

• Complex reaction

• Neutral reaction

• None of the above

The reaction in which rate of reaction not depend upon concentration of reactant is

• First order reaction

• Second order reaction

• Zero order reaction

• None of the above

if the order of a reaction with respect to a reactant, A, is zero order, this means that

• A is a catalyst

• A is not involved in the overall reaction

• the value of the rate constant does not depend on A

• the rate of reaction is not affected by a change in the concentration of A
