Question

Which of the following correctly describes the decomposition of aqueous NaNO3?

Answer 1

The option that is more likely to happen is The molar enthalpy is 447 kJ and the reaction is endothermic. We can say this because decomposition reaction need more energy input than output and when this is the case, a reaction is given to be endothermic and when energy is given in, the value is positive. Hope this info can help you
