when we have the balanced reaction equation is:

H2(g)  + CO2(g) ↔ H2O(g)  + CO (g)

a) first, to calculate ΔG° for the reaction: 

we will use this formula:

ΔG° = -RT㏑Kp

when R is R- rydberg constant = 8.314J/mol.K

and T is the temperature in Kelvin = 2000 K

and Kp = 4.4 

so, by substitution:

ΔG° = - 8.314 *2000 *㏑4.4

        = - 24624 J/mol = - 24.6 KJ/mol

b) to calculate ΔG so, we will use this formula:

ΔG = ΔG° + RT㏑Qp

So we need first, to get Qp from the reaction equation:

when Qp = P products / P reactants

                 =  PH2O*PCO / PH2 * PCO2

                 = (0.66 atm * 1.2 atm) / (0.25 * 0.78)

                 = 4.1 

so by substitution:

ΔG = -24624 + 8.314*2000*㏑4.1

      = -1162 J/mol = - 1.16 KJ/mol

When there is a balanced equation then:

H2 (g) + CO2 (g) ↔ H2O (g) + CO (g)

Further Explanation

a) first, to calculate ΔG ° for the reaction:

we will use this formula:

ΔG ° = -RT㏑Kp

when R is that the constant Rydberg = 8,314J / mol.K

and T is that the temperature at Kelvin = 2000 K

and Kp = 4.4

so, by substitution:

ΔG ° = - 8,314 * 2000 * ㏑4.4

= - 24624 J / mol = - 24.6 KJ / mol

b) to calculate ΔG so, we'll use this formula:

ΔG = ΔG ° + RT㏑Qp

So we first have to, to induce Qp from the reaction equation:

when Qp = product P / reactant

= PH2O * PCO / PH2 * PCO2

= (0.66 atm * 1.2 atm) / (0.25 * 0.78)

= 4.1

so with substitution:

ΔG = -24624 + 8,314 * 2000 * ㏑4.1

= -1162 J / mol = - 1.16 KJ / mol

A chemical reaction is a natural process that always produces interchange of chemical compounds. The initial compounds or compounds involved in the reaction are called reactants. Chemical reactions are usually characterized by chemical changes and will produce one or more products that usually have different characteristics from reactants.
