Adilute aqueous solution of sulfuric acid at 25°c is used to absorb ammonia in a continuous reactor, thereby producing ammonium sulfate, a fertilizer:
2nh3(g) + h2so4(aq) ? (nh4)2so4(aq)
a)if the ammonia enters the absorber at 75°c. the sulfuric acid enters at 25°c, and the product solution emerges at 25°c, how much heat must be withdrawn from the unit per mol of (nh4)2so4 produced?
b)estimate the final temperature if the reactor of part (a) is adiabatic and the product of the solution contains 1.00 mole % ammonium sulfate. take the heat capacity of the solution to be that of pure liquid water [4.184 kj/(kg·°c)].
