Dalton’s law of partial pressure states that the total pressure exerted by a mixture of gas and vapour is the sum of partial pressure of the gas and partial pressure of the vapour at the common temperature.

Correct Answer: True
The given statement is the correct one for Dalton’s law of partial pressure. Therefore, at a particular temperature ‘t’ – Mathematically, P = Pa + Ps Where, P = Total pressure inside the container Pa = Partial pressure of the gas (at temperature t) Ps = Saturation pressure of water at temperature t

The highest pressure gas of a mixture has partial pressure p, the partial pressure of other gases decreases by factor of 2n-1, the partial pressure of second gases decreases by a factor of 2, partial pressure of third gas increases by 4, and so on, if the total pressure of gas mixture is 31p/16, how many gases are present in the mixture?

Consider the following statements and choose the correct answer:
1. A direct proportionality exists between vapour pressure and the concentration of water vapour in the atmosphere
2. Relative humidity is an expression of the ratio of the actual vapour pressure of the atmosphere when saturated at the same temperature
3. A rise or fall in temperature with no change in vapour pressure will cause a drop or rise, respectively, in relative humidity
4. A rise or fall in vapour pressure with no change in temperature will be accompanied by a rise or fall, respectively, in relative humidity

According to Dalton's law of partial pressures, (where pb = Barometric pressure, pa = Partial pressure of dry air and pv = Partial pressure of water vapour)

The Henry’s law constant for O2 in water at 25°C is 1.27×10−3M/atm and the mole fraction of O2 in the atmosphere is 0.21. Calculate the solubility of O2 in water at 25°C at an atmospheric pressure of 1.00 atm. Strategy: ▪ Use Dalton’s law of partial pressures to calculate the partial pressure of oxygen. ▪ Use Henry’s law to calculate the solubility, expressed as the concentration of dissolved gas.

Which of the following statements about partial pressure are correct? Statement 1: The partial pressure of each gas in a mixture is not proportional to its mole fraction.. Statement 2: The partial pressure of each gas is the product of the total pressure and the mole fraction of that gas.

An air-water vapour mixture has a dry bulb temperature of 60°C and a dew point temperature of 40°C. The total pressure is 101.3 kPa and the vapour pressure of water at 40°C and 60°C are 7.30 kPa and 19.91 kPa respectively.The humidity of air sample expressed as kg of water vapour/kg of dry air is

Saturated solution of benzene in water is in equilibrium with a mixture of air and vapours of benzene and water at room temperature and pressure. Mole fraction of benzene in liquid is xB and the vapour pressures of benzene and water at these conditions are PvB and Pvw respectively. The partial pressure of benzene in air-vapour mixture is

The ratio of partial pressure of the vapour in the gas mixture and the vapour pressure of the vapour component is called

Condensation of a vapour-gas mixture just begins, when (where, p = partial pressure of the vapour, P = vapour pressure of the liquid)

According to the Dalton’s law of partial pressures, the total pressure of a mixture of ideal gases is equal to the
