the reaction a(g) ⇌ b(g) has an equilibrium constant that is less than one. what can you conclude about ∆g° for the reaction?
-Dominant- [34]

For this reaction: ΔG⁰>0.

Balanced chemical reaction A(g) ⇌ (g)

ΔG° indicates that all reactants and products are in their standard states.

ΔG° = R·T·lnK.

ΔG° is Gibbs free energy

T is the temperature on the Kelvin scale

R is the ideal gas constant

The equilibrium constant (K) is the ratio of the partial pressures or the concentrations of products to reactants.

Gibbs free energy (G) determines if reaction will proceed spontaneously, nonspontaneously or in equilibrium processes.

If K < 1, than ΔG° > 0.

Reactants (in this example A) are favored over products (in this example B) at equilibrium.

The following equation shows the equilibrium in an aqueous solution of ammonia: NH3(aq)+H2O(l)⇌NH4+(aq)+OH−(aq)NH3(aq)+H2O(l)⇌NH
yarga [219]

Answer:

c) H2O and OH−

Explanation:

Acids are the species which furnish hydrogen ions in the solution or is capable of forming bonds with electron pair species as they are electron deficient species.

When an acid donates a proton, it changes into a base which is known as its conjugate base.

Bases are the species which furnish hydroxide ions in the solution or is capable of forming bonds with electron deficient species as they are electron rich species. When a base accepts a proton, it changes into a acid which is known as its conjugate acid.

The acid and the base which is only differ by absence or presence of the proton are known as acid conjugate base pair.

Thus,  for the reaction,

NH_3+H_2O\rightleftharpoons Nh_4^++OH^-

The base is NH_3 and the conjugate acid of the base is NH_4^+.

Also, The base is OH^- and the conjugate acid of the base is H_2O.

<u>Correct option is :- c) H2O and OH−</u>
