For the reaction, \(\mathrm{H}_2 \mathrm{O}(l) \longrightarrow \mathrm{H}_2 \mathrm{O}(\mathrm{g})\) at \(T=100^{\circ} \mathrm{C}\) and \(p=1 \mathrm{~atm}\), choose the correct option.

Find the approximate value of \((\Delta H-\Delta U)\) in \(\mathrm{Jmol}^{-1}\), for the formation of CO from its elements at \(298 \mathrm{~K} .\left(R=8.314 \mathrm{JK}^{-1} \mathrm{~mol}^{-1}\right)\)

When an ideal gas expands isothermally from \(5 \mathrm{~m}^3\) to \(10 \mathrm{~m}^3\) at \(25^{\circ} \mathrm{C}\) against a constant pressure of \(10^7 \mathrm{~Nm}^{-2}\), then the work done on the gas is

If a chemical reaction is known to be
non-spontaneous at 298 K but spontaneous
at 350 K, then which among the following
conditions is true for the reaction?

When the temperature of 2 moles of an ideal
gas is increased by 20\(^\circ\)C at constant pressure.
Find the work involved in the process.

Two flasks \(A\) and \(B\) have equal volumes. \(A\) is maintained at \(300 \mathrm{~K}\) and \(B\) at \(600 \mathrm{~K}\). Equal masses of \(\mathrm{H}_2\) and \(\mathrm{CO}_2\) are taken in flasks \(A\) and \(B\) respectively. Find the ra...
