Use the free energies of formation given below to calculate the equilibrium constant (k) for the following reaction at 298 k. 2 hno3(aq) + no(g) → 3 no2(g) + h2o(l) k = ? δ g0f(kj/mol) -110.9 87.6 51.3 -237.1

The equilibrium constant K = 1.15*10^-9

Explanation:

Given:

ΔG°f(HNO3) = -110.9 kj/mol

ΔG°f(NO) = 87.6 kj/mol

ΔG°f(NO2) = 51.3 kj/mol

ΔG°f(HNO3) = -237.1 kj/mol

To determine:

The equilibrium constant (K) for the given reaction

Calculation:

The chemical reaction is:

The equation that relates the standard free energy change ΔG° to the equilibrium constant K is:

(or)

where R = gas constant = 8.314 J/mol-K

T = temperature in Kelvin

where n(p) and n(r) are the number of moles of the products and reactants respectively

Therefore for the given reaction:

Substituting the given values for ΔG°f:

ΔG° = + 51 kJ

Substituting the calculated ΔG° in equation (1) at T = 298 K gives:

no, i was listening to water by schoolboy q while and i saw this question

explenation:

water isn't wet. wetness is a description of our experience of water; what happens to us when we come into contact with water in such a way that it impinges on our state of being. we, or our possessions, 'get wet'. a less impinging sense experience of water is that it is cold or warm, while visual experience tells us that it is green or blue or muddy or fast-flowing. we learn by experience that a sensation of wetness is associated with water: 'there must be a leak/i must have sat in something.'
