For a reversible process, the following equation describes the entropy changes of the universe, system, and surroundings.δsuniv = δssys + δssurr = 0for an irreversible process, the following equation applies.δsuniv = δssys + δssurr > 0for each of the following processes, predict whether δssurr is positive, negative, or zero.(a) isothermally expanding a gas, δssys > 0(b) reacting hydrogen and oxygen gas, δssys < 0 step 1 of 3identify each process as reversible or irreversible.(a) this process is (reversible or irriversible) because it (possible or impossible) to exactly reverse the change by compressing the gas isothermally.(b) this process is (reversible or irriversible) because it is spontaneous and (can or cannot) be reversed by simply reversing the process.
