List of top Chemistry Questions on The Kinetic Theory of Gases asked in JEE Main

The correct order of molar heat capacities measured at 298 K and 1 bar is :

At \( 27^\circ \text{C} \), 0.1 M, 1 L \( K_4[Fe(CN)_6] \) aqueous solution and 0.1 M, 1 L \( FeCl_3 \) aqueous solution are placed in a container separated by a semi permeable membrane AB. Assume complete dissociation of both the solutes. Which of the following statement is correct?

Statement I: For an ideal gas, heat capacity at constant volume is always greater than the heat capacity at constant pressure.
Statement II: In a constant volume process, no work is produced and all the heat withdrawn goes into the chaotic motion and is reflected by a temperature increase of the ideal gas.
In the light of the above statements, choose the correct answer:

Consider the transition metal ions \( \text{Mn}^{3+}, \text{Cr}^{3+}, \text{Fe}^{3+} \) and \( \text{Co}^{3+} \) and all form low spin octahedral complexes. The correct decreasing order of unpaired electrons in their respective \(d\)-orbitals of the complexes is

Which of the following graph correctly represents the plots of \(K_H\) at 1 bar gases in water versus temperature?

A home owner uses \(4.00 \times 10^3 \text{ m}^3\) of methane (\(CH_4\)) gas, (assume \(CH_4\) is an ideal gas) in a year to heat his home. Under the pressure of 1.0 atm and 300 K, mass of gas used is \(x \times 10^5\) g. The value of \(x\) is ________. (Nearest integer) (Given R = 0.083 L atm \(K^{-1} mol^{-1}\))
