conditions that would favour maximum conversion of nitrogen (II) oxide and carbon (II) oxide in the reaction above?
are; i low temperature since the forward reaction is endothermic and backward reaction is exothermic.
ii high pressure since forward reaction involves a reduction in volume and backward reaction involves an increase in volume. ( reaction is in the gaseous phase).
