Gibbs free energy (g) is a measure of the spontaneity of a chemical reaction. it is the chemical potential for a reaction, and is minimized at equilibrium. it is defined as g=h−ts where h is enthalpy, t is temperature, and s is entropy. the chemical reaction that causes magnesium to corrode in air is given by 2mg+o2→2mgo in which at 298 k δh∘rxn = −1204 kj δs∘rxn = −217.1 j/k part a what is the standard gibbs free energy for this reaction? assume the commonly used standard reference temperature of 298 k. express your answer as an integer and include the appropriate units. view available hint(s) δg∘rxnδ g r x n ∘ = nothing
