Missing question: A sealed vessel, containing nitrogen dioxide and carbon dioxide gases has a total pressure of 2558 psi.

total pressure = partial pressure of nitrogen dioxide + partial pressure of carbon dioxide.
p(total) = 2558 psi; total pressure.
p(CO₂) = 795 psi; partial pressure of carbon dioxide.
p(NO₂) = p(total) - p(CO₂); partial pressure of nitrogen dioxide
p(NO₂) = 2558 psi - 795 psi.
p(NO₂) = 1763 psi(pound-force per square inch).
p(NO₂) = 121.55 bar.

answer: - 3.) the oxidation state of nitrogen in no changes from +2 to 0, and the oxidation state of carbon in co changes from +2 to +4 as the reaction proceeds.

solution: - as per the rules, oxidation number of oxygen in its compounds is -2. the sum of oxidation numbers of all the elements of a molecule or compound is zero.

also, the oxidation number in elemental form is zero.

in no, the oxidation number of o is -2 so the oxidation number of n is +2 so that the sum is zero.

similarly, the oxidation number of c in co is +2 and o is -2.

on product side the oxidation number of n is 0 as it is in the elemental form( $n_2$ ) .

oxidation number of c in carbon dioxide is +4 as there are two oxygen in it and we know that each oxygen is -2.

so, oxidation number of n is changing from +2 to 0 and the oxidation number of c is changing from +2 to +4.

since nitrogen is reduced and hence no is acting as an oxidizing agent. carbon is oxidized and so co is acting as a reducing agent.

so, the right choice is number 3.)the oxidation state of nitrogen in no changes from +2 to 0, and the oxidation state of carbon in co changes from +2 to +4 as the reaction proceeds.
