The standard Gibbs energy change for the following reaction is 23 kj mol-1 at 298 k what are the concentrations of ca2 and so42- at equilibrium is 3032K.

What is Gibbs energy ?

The Gibbs free energy, also referred to as the Gibbs function, Gibbs energy, or free enthalpy, is a unit of measurement used to determine the maximum amount of work that can be accomplished in a thermodynamic system when the temperature and pressure are held constant.

What is equilibrium ?

Chemical equilibrium is characterized as a dynamic condition in which the concentration of each reactant remains constant. Even if they aren't equal, they aren't altering. An equilibrium state in a chemical reaction is denoted by a double arrow. Left are reactants, and right are products.

ΔG∘=−1486kJ/mol

T=3032K

ΔG∘=ΔH∘−TΔS∘

Under standard conditions T=298K

∴ΔG∘=−1648.4×10³−(298×−543.7)

ΔG∘=−1486 kJ/mol

At equilibrium ΔG=0

∴0=ΔH∘−TΔS∘

assuming the enthalpy and entropy changes don't change much with temperature we can use the standard values.

∴T=ΔH∘ΔS∘

T=−1648.4×10³−543.7K

T=3032K

Therefore, standard Gibbs energy change for the following reaction is 23 kj mol-1 at 298 k what are the concentrations of ca2 and so42- at equilibrium is 3032K.
