The first quantitative relationship between the rate of reaction and concentration of reactants was given by
Goldstein
Guldberg and waage.
Lavoisier.
Chadwick.
The average rate of the reaction is given by
Change in concentration/Time taken for the change
Time taken for the change/ Change in concentration
Time taken for the change/change in concentration of a reactant or a product.
Change in concentration of a reactant or a product/ Time taken for the change.
The rate of a reaction may be ___________________ by increasing the concentration of one or more reactants.
Decreased
Increased.
May be increased or decreased
Constant.
The rate of a chemical reaction
Increases as the reaction proceeds
Decreases as the reaction proceeds.
May increase or decrease during the reaction.
Remains constant as the reaction proceeds.
The branch of chemistry which deals with the study of reaction rates and their mechanism is called
Chemical reaction
Chemical kinetics.
Chemisorption.
Chemical reactants.
___________ reaction is termed as slow reaction.
Molecular reaction.
Homogeneous reaction.
Ionic reaction
Heterogeneous reaction.
The rate of a reaction between two substances depends upon the ________________ between their molecules.
Collision theory of reaction rate
Specific reaction rate
Rate of collision.
Rate constant.
The rate of reaction determined at a particular moment is called
Instantaneous rate
Chemical reaction rate.
The rate of reaction=
Change in concentration/Time taken for the change.
The rate of a reaction involving a solid reactant ______________ with increase in the surface area of the substance.
Decreases
Increases.
May be increases or decreases
