"MOLE FRACTIONS IN SO2 OXIDATION TO SULFURIC ACID. ■ y SO2 + y/2 O2 = z SO3 ■ An initial gas mixture of Y moles SO2 and Y/2 moles O2 yields Z moles of SO3 at equilibrium at a total pressure of P. Let Q = Z/Y, the fractional conversion of SO2 to SO3. The equations for the equilibrium mole fractions of X[i] of each species are presented in terms of Q. The equilibrium constant Kp is given in terms of X[i] and P. *** Answer(s) to Problem(s) **** (c) Copyright PCSCC, Inc., 1993Set Q=0, and P= 1 (atmosphere). The solve function S will be used to solve for Qsuch that KP equals 1/P^2 or KP=1. Move cursor to variable Q and type S. Select KP by typing (end esc) KP (enter). For value, type (end esc) 1 (enter). Use default search range, type (enter).
