Which of the following is a correct analysis of the isothermal reactor, compared to the adiabatic reactor?
A feed stream of 50 mol% A and 50 mol% B at 500 K enter an adiabatic steady state reactor. The reaction is A + B ? C and occurs in the liquid phase. The stream leaving the reactor is at 545 K, and is at equilibrium. An engineer proposes adding temperature control to the reactor, so that it is instead an isothermal reactor at 500 K A. The reaction will be slower in the isothermal reactor, but the effect on the extent of reaction at equilibrium cannot be determined. B. The reaction will be slower in the isothermal reactor, and the extent of reaction at equilibrium will be lower than in the adiabatic reactor. C. The reaction will be slower in the isothermal reactor, but if the reaction reaches equilibrium, the extent of reaction will be higher than in the adiabatic reactor. D. It is unrealistic for a reaction to occur in the liquid phase at temperatures of 500 K and above. E. None of the above are accurate.
What is the purpose of cooling tower fill material?
A) Increases the rigidity of the cooling tower structure B) Slows the falling water and increases the surface exposure for evaporation C) Provides a growing surface for algae and plants that help clean the water D) Filters out dirt and debris from the cooling tower water
