Which of the following statements is incorrect about the equation?

${\mathrm{C}}_2{\mathrm{H}}_5\mathrm{OH}\left(\mathrm{l}\right)+3{\mathrm{O}}_2\left(\mathrm{g}\right)⟶2{\mathrm{CO}}_2\left(\mathrm{g}\right)+3{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)$

${\mathrm{\Delta }}_{\mathrm{r}}{\mathrm{H}}^{\circ }=-1367\mathrm{kJ}{\mathrm{mol}}^{-1}$

The numerical value of ${\mathrm{\Delta }}_{\mathrm{r}}{\mathrm{H}}^{\circ }$ refers to the number of moles of substances specified by an equation.

The equation describes the combustion of liquid ethanol at constant temperature and pressure.

The reaction is an endothermic

The coefficients in a balanced thermochemical equations refer to the number of moles (never molecules) of reactants and product involved in the reaction
