Answers to certain problems from Chapter 6
Problem 6.12
a) P*= 731.4 mmHg.
b)
% condensation =99.7%
c)
Assumptions:
(1) Raoult’s law holds at initial and final conditions;
(2) CB is the only condensable species (no water condenses);
(3) Clausius-Clapeyron estimate is accurate at 130°C.
Problem 6.22
a) molar flow rate:6.53kmol/hr
b)T= 34.8 C

Unformatted text preview: c) T= 2.52 C Problem 6.56 a) n BO = 0.0962 mol B(v)/min n TO = 0.0962 mol T(v)/min b) Since benzene is evaporating more rapidly than toluene, x B decreases with time and x T (= 1– x B ) increases. c. Since x B decreases, y B (= x B p B */ P ) also decreases. Since x T increases, y T (= x T p T */ P ) also increases....
