For which of the following gas mixtures does Dalton's law of partial pressure $NOT$ apply?

$A$ $10 \ L$ vessel contains $1 \ mole$ of an ideal gas with pressure of $P \ atm$ and temperature of $T \ K$. The vessel is divided into two equal parts. The pressure (in $atm$) and temperature (in $K$) in each part is respectively:

$A$ closed container contains a mixture of non-reacting gases $A$ and $B$. The partial pressures of $A$ and $B$ are $4.5 \ bar$ and $5.5 \ bar$ respectively. Find the mole fractions of $A$ and $B$ respectively.

$1 \ L$ each of gases $A$ and $B$ diffused through a membrane in $15$ and $30$ minutes, respectively, under identical conditions. What is the ratio of molecular weight of $A$ and $B$?

Under standard conditions of temperature and pressure,what will be the ratio of the rate of diffusion of helium to methane?

Which state of matter has a definite volume but no definite shape?
