Consider the Gibbs-Helmholtz equation, G = H - TS. For each dissolving process, substitute the signs of G and H into the equation and predict the sign for the entropy (S). Does the sign for entropy change seem to make sense? Explain.

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.

what does the table look like

the answer is na (sodium)
