Steam at 2700 kPa and with a quality of 0.90 undergoes a reversible, adiabatic expansion in a nonflow process to 400 kPa. It is then heated at constant volume until it is saturated vapor. Determine Q and W for the process.

What is the primary difference between enzymatic and non-enzymatic reactions in chemical engineering? a) Enzymatic reactions involve catalysts, while non-enzymatic reactions do not. b) Enzymatic reactions are slower compared to non-enzymatic reactions. c) Enzymatic reactions are reversible, while non-enzymatic reactions are irreversible. d) Enzymatic reactions require higher temperatures and pressures compared to non- enzymatic reactions.

For each of the endothermic and exothermic reactions, explain which reactor type is optimal for adiabatic operation.
