Which of the given sets of temperature and pressure will cause a gas to exhibit the greatest deviation from ideal gas behaviour?
Which among the following gases can be liquified easily? |
Answer |
One mole of oxygen at 273 K and one mole of sulphur dioxide at 546 K are taken in two separate containers, then, |
Answer |
For one mole of an ideal gas the slope of V vs. T curve at constant pressure of 2 atm is X lit mol–1 K–1. The value of the ideal universal gas constant ‘R’ in terms of X is |
Answer |
If 10–4 dm3 of water is introduced into a 1.0 dm3 flask at 300 K, how many moles of water are in the vapour phase when equilibrium is established? |
Answer |
In two vessels of 1 L each at the same temperature 1 g of H2 and 1 g of CH4are taken, for these |
Answer |
Which one of the following statements is NOT true about the effect of an increase in temperature on the distribution of molecular speeds in a gas? |
Answer |
What volume of oxygen gas (O2) measured at 0°C and 1 atm, is needed to burn completely 1 litre of propane gas (C3H8) measured under the same conditions? |
Answer |
‘n’ mole of an ideal gas at temperature T (in Kelvin) occupy ‘V’ litres of volume, exerting a pressure of ‘P’ atmospheres. What is its concentration (in mole.lit)? (R = gas constant) |
Answer |
10g each of CH4 and O2 are kept in cylinders of same volume under same temperatures, give the pressure ratio of two gases. |
Answer |
The hydrides of the first elements in groups 15 – 17, namely NH3, H2O and HF respectively show abnormally high values for melting and boiling points. This is due to |
