$$K_p$$ value for $$2SO_{2(g)} + O_{2(g)} \rightleftharpoons 2SO_{3(g)}$$ is $$5.0 atm^{-1}$$. What is the equilibrium partial pressure of $$O_2$$ if the equilibrium pressures of $$SO_2$$ and $$SO_3$$ are equal?

A mixture of ethyl alcohol and propyl alcohol has vapour pressure of $$290mm$$ at $$300K$$. The vapour pressure of propyl alcohol is $$200mm$$. If mole fraction of ethyl alcohol is $$0.6$$ its vapour presssure at same temperature will be:-

The value of the molar gas constant is:

The amount of solute (mol mass=$$60$$) that must be added to $$180g$$ of water so that the vapour pressure of water is lowered by $$10 \%$$ is?

1litre of a gas weights 2g at 300K and 1atm pressure.If the pressure is made 0.75atm at which temperature will 1L of same gas weighs 1g ?

At what temperature, the sample of neon gas would be heated to double its pressure initial volume of gas is reduced by 15% at $$75^{0}C $$?

How much pressure will be felt by a gas ballon which at 100 m depth in a sea form sea level?

$$Mg + H_2SO_4 \rightarrow MgSO_4 + H_2$$
In this reaction, which mass of magnesium sulphate is formed when 6g of magnesium react with excess sulphuric acid?

Which is not true in case of an ideal gas?

The vapour pressure of water is $$12.3k \, Pa$$ at $$300K$$. Calculate the vapour pressure $$1$$ molal solution of a non-volatile solute in it.
