Answer: 10.84 moles of $CO_2$ will be produced from complete combustion of 5.42 moles of ethanol

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number $6.023\times 10^{23}$ of particles.

$2C_2H_6O+7O_2\rightarrow 4CO_2+6H_2O$

According to stoichiometry :

2 moles of ethanol produce = 4 moles of $CO_2$

Thus 5.42 moles of ethanol will produce= $\frac{4}{2}\times 5.42=10.84moles$ of $CO_2$

Thus 10.84 moles of $CO_2$ will be produced from complete combustion of 5.42 moles of ethanol

It is achievable for the same enzyme to catalyze reverse reactions for the reason that the direction of a reversible reaction is determined by the concentrations of reactants and products. In pulmonary circulation, the low CO2 concentration supports the making of CO2 and H2O.
