Question

Statement-1 : Volume of a gas is inversely proportional to
the number of moles of gas.
Statement-2 : The ratio by volume of gaseous reactants and
products is in agreement with their mole ratio.

Answer 1

Answer:

Both Statements are true and Statement 2 is the

explanation of Statement 1

Answer 2

Statement-1 is false and statement-2 is true

Explanation:

According to the given statement-1, Volume of a gas is inversely proportional to  the number of moles of gas. This is a false statement because the volume of a gas is always directly proportional to its number of moles. This is explained by Avogadro's law.

And the statement-2 is The ratio by volume of gaseous reactants and

products is in agreement with their mole ratio. This is true.

For example,

$H_2+Br_2 \to 2HBr$

In this reaction, the ratio of reactants and product volumes is 1:1:2 which is same as their number of moles.

Hence, Statement-1 is false and statement-2 is true
