Coal can be used to generate hydrogen gas (a potential fuel) by the following endothermic reaction:

C(s)+H2O(g) ⇌ CO(g)+H2(g)C(s)+H2O(g)⇌CO(g)+H2(g)

If this reaction mixture is at equilibrium, predict whether each of the following will result in the formation of additional hydrogen gas, result in the formation of less hydrogen gas, or have no effect on the quantity of hydrogen gas.

(a) adding more C to the reaction mixture
(b) adding more H2O to the reaction mixture
(c) raising the temperature of the reaction mixture
(d) increasing the volume of the reaction mixture
(e) adding a catalyst to the reaction mixture
(f) adding an inert gas to the reaction mixture

they are both synthetic elements

explanation:

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.

c) should be the answer.
