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.
