Astudent adds 0.1 mol of oxalic acid and 0.1 mol of sodium dihydrogen phosphate to enough water to make 1.0 l of solution. the following equilibrium is established with the concentrations of the products greater than the concentrations of the reactants. which of the statements about the equilibrium system is correct?
h2c2o4(aq) + h2po4-(aq) hc2o4-(aq) + h3po4(aq)
a) oxalic acid is a weaker acid than phosphoric acid.
b) the hydrogen oxalate anion, hc2o4-, is a stronger base than the dihydrogen phosphate anion, h2po4- .
c) phosphoric acid is a weaker acid than oxalic acid.
d) the dihydrogen phosphate anion, h2po4-, is a stronger acid than oxalic acid.
e) water is a stronger acid than either oxalic or phosphoric acids.

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
