1. explain the second law of thermodynamics and its significance. 2.what are the difference between enthalphy and entropy

3. what are the conditions for spontaneous change

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.

the answer is option a.

it’s previous models   because when i picked that son of a gun’s answer it was wrong look for previous models because they might make it a different letter
