CuSO$$_4.$$5$$H_2O$$(s) $$\rightleftharpoons$$ CuSO$$_4$$.3H$$_2O$$(s) + 2H$$_2O$$(g); $$k_p$$ = 4 $$10^{4}$$ atm$$^2.$$ If the vapour pressure of water is 38 torr then percentage of relative humidity is : (Assume all data at constant temperature)

Vapour Pressure of a mixture of benzene and toluene is given by $$P= 179X_{B} + 92$$, Where $$X_{B}$$ is mole fraction of benzene.
This condensed liquid again brought to the same temperature then what will be the mole fraction of benzene in vapour phase :

What is the effect on the pressure of a gas if its temperature is increased at constant volume?

$$100$$ grams of oxygen $$(O_{2})$$ gas and $$100$$ grams of helium $$(He)$$ gas are in separate containers of equal volume at $$100^{\circ}C$$. Which one of the following statement is correct?

What is a weight of $$CO_2$$ in a $$10L$$ cylinder at $$5atm$$ and $$27^0C$$?

$$X,Y$$ and $$Z$$ in the given graph are?

A container of $$1\ L$$ capacity contains a mixture of $$4\ g$$ of $$O_{2}$$ and $$2\ g$$ of $$H_{2}$$ at $$0^{\circ}C$$. What will be the total pressure of the mixture?

A plot of volume $$(V)$$ versus temperature $$(T)$$ for a gas at constant pressure is a straight line passing through the origin. The plots at different values of pressure are shown in figure. Which of the following order of pressure is correct for this gas?

If the ratio of masses of $$SO_{3}$$ and $$O_{2}$$ gases confined in a vessel is $$1 : 1$$, then the ratio of their partial pressures would be :

A $$2\ L$$ vessel is filled with air at $$50^{\circ}C$$ and a pressure of $$3\ atm$$. The temperature is now raised to $$200^{\circ}C$$. A valve is now opened so that the pressure inside drops to one atm. What will be the fraction of the total number of moles, inside escaped on opening the valve? (Assume no change in the volume of the container).
