According to law of mass action rate of a chemical reaction is proportional to
1 Concentration of reactants
2 Molar concentration of reactants
3 Concentration of products
4 Molar concentration of products
Explanation:
(b) According to law of mass-action, “at a given temperature, the rate of a reaction at a particular instant is proportional to the product of the active masses of the reactants at that instant raised to powers which are numerically equal to the numbers of their respective molecules in the stoichiometric equation describing the reaction”.

In a reaction the rate of reaction is proportional to its active mass, this statement is known as
1 Law of mass action
2 Le-chatelier principle
3 Faraday law of electrolysis
4 Law of constant proportion
Explanation:
Law of mass action states that rate of a chemical reaction is proportional to the concentration to the reacting substances. Concentration $=$ active mass.

The active mass of \(64\, gm\) of \(HI\) in a two litre flask would be
1 \(2\)
2 \(1\)
3 \(5\)
4 \(0.25\)
Explanation:
(d) \([HI] = \frac{{64\,gm}}{{128 \times 2\,litre}} = 0.25\) Active mass is the concentration in moles/litre.

Under a given set of experimental conditions, with increase in the concentration of the reactants, the rate of a chemical reaction
1 Decreases
2 Increases
3 Remains unaltered
4 First decreases and then increases
Explanation:
Under a given set of experimental conditions, with an increase in the concentration of the reactants the rate of a chemical reaction increases. rate \(= k [ A ]^{ n }\) However, this is not true for a zero-order reaction as the rate of the reaction is independent of concentration. rate \(= k [ A ]^0\)
