Thermodynamics

Gaseous Nitrous oxide decomposes at \(298 \mathrm{~K}\) to form Nitrogen gas and Oxygen gas. The \(\Delta \mathbf{H}\) for the reaction at \(1.0 \mathrm{~atm}\) pressure and \(298 \mathrm{~K}\) is \(\mathbf{- 1 6 3 . 1 5} \mathbf{~ k J}\). Calculate Internal energy change for the decomposition of \(100 \mathrm{~g}\) of Nitrous oxide gas under the same conditions of temperature and pressure.
