The entropy change for the formation of 1 mol of C 2 H 2 ( g ) from hydrogen and carbon under standard conditions has to be calculated. Concept Introduction: The term entropy is used to represent the randomness in a system. When a system moves from an ordered arrangement to a less ordered arrangement, then the entropy of the system increases. The second law of thermodynamics state that “the entropy of the system either increases or remains the same.”

The reaction is carried out with gases: A → B + C at 300 K. The
total pressure is measured as a function of time (table). If the
reaction order is 2, calculate the rate or kinetic constant k (in
