It orders the chemical elements in a useful way.
<h3><u>Answer;</u></h3>
increase the partial pressure of CO2
<h3><u>Explanation;</u></h3>
2CO(g) + O2(g) -------> 2CO2(g) + heat
- Removel of Oxygen makes the equilibrium to move towards the left side (reactants) because the reactants concentration is decreasing. According to the LeChâtelier’s principle equilibrium moves towards the lower concentration.
- When the partial pressure of any of the gaseous reactants or of the products is increased, the position of equilibrium is shifted so as to decrease its partial pressure. In this case, the removal of oxygen causes a shift to to the left which causes an increase in the partial pressure of CO2.
The formula of citric acid is:
CO2H

HO - C - CH2CO2H

C - CH2 CO2H
I bolded the 4 hydrogens that can be subsituted by sodium.
Three of those hydrogens belong to carboxyl group (- CO2H) and one to a hydroxyl group (- OH).
You need to take into account that 4 H will form 2 H2 molecules.
So, the answer is that 2 moles of molecules will be formed from 1 mole of citric acid molecules.
