For gases initially contained in a 1.0 L vessel and the reaction 2 NO2(g) N2O4(g) H = 37.

For gases initially contained in a 1.0 L vesseland the reaction2 NO2(g) ↽⇀ N2O4(g)∆H◦= −37.7 kJ/mol,which of the following would NOT cause theequilibrium to shift to the left and convertsome N2O4 to NO2?I. addition of 1 mol He(g) to the vessel;II. isothermally decreasing the volume ofthe container to 0.425 L;III. addition of 1 mol of N2O4(g);IV. increasing the temperature;
