Acetic acid and methyl alcohol react together to form
CH3OH + H
CH3OH + H2O + CO2.
CH3COOH + H
CH3COOCH3 + H2O
The rate of reaction determined at a particular moment is called
Instantaneous rate
Rate constant.
Specific reaction rate
Chemical reaction rate.
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.
________________ is used to explain the dependence of reaction rate on concentration.
Law of conversation of mass.
Law of constant composition.
Law of mass action
Law of multiple proportions.
For most of the homogeneous reaction the value of temperature coefficient lies between
1 and 2
2 and 3.
3 and 4.
4 and 5.
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
