CBE 102B Problem Set 4 [ABET] Due: Friday, April 30, 2010 1.(20 pts.) Consider the ideal gas reaction: 222H (g)CO (g)CO(g)H O(g)++R. At 1000 K, a measurement gives the following values for the partial pressures: () ( )( ) ( )2H0.55bar ,CO0.20bar ,CO1.25bar ,H O0.10barpp pp====. Is the reaction at equilibrium under these conditions? If not, in what direction will the reaction proceed to attain equilibrium? 2.(30 pts.) Consider the ideal gas reaction A(g)3B(g)2C(g)+R. Assuming that the initial mixture contains A(g) and B(g) in stoichiometric proportions (1 and 3 moles respectively), find an expression for the equilibrium extent of the reaction, ξ, as a function of the total pressure, p, at fixed temperature. 3.(20 pts.) Consider the ideal-gas reaction: . If the initial mixture contains 1 mole of N
