02/01/2019· A compound ''C'' with molecular formula C2H4O2 reacts with Na metal to form compound ''R'' and evolve a gas which burns with pop sound. ''C'' reacts with an alcohol ''A'' in presence of an acid to form a compound C2H4O2. On addition of NaOH to ''C'' it gives ''R'' and water. ''S'' on treatment with NaOH gives back ''R'' and ''A''.

Enthalpy and Chemical Reactions – Introductory …

The enthalpy change for a reaction is typically written after a balanced chemical equation and on the same line. For example, when two moles of hydrogen react with one mole of oxygen to make two moles of water, the characteristic enthalpy change is 570 kJ. We write the equation as. 2 H 2 (g) + O 2 (g) → 2 H 2 O(ℓ) ΔH = −570 kJ

Gibbs Free Energy - Definition, Equations, 2nd Law of

Gibbs Free Energy Equation. Gibbs free energy is equal to the enthalpy of the system minus the product of the temperature and entropy. The equation is given as; G = H – TS. Where, G = Gibbs free energy. H = enthalpy. T = temperature. S = entropy. Gibbs free energy is a state function hence it doesn’t depend on the path.
