ChE102 Chemistry for Engineers - Tutorial 7 SolutionsSolve the following problems either individually or in small groups (3 students maximum). Submit one copy of the solutions per group. Ask the TA for help if you need assistance solving the problems. Problem 1Consider the successive gas phase reactions: 3A(g) 2B(g) (1)B(g) + C(g) D(g)(2) The equilibrium constants for these reactions at 500. K are Kp,1= 6.0932 and Kc,2= 10.0. a) What is the value of Kcfor the overallreaction at 500. K? b) What is the value of Kpfor the overallreaction at 500. K? Solution

Problem 2Consider the following gas phase reaction: A(g) + B(g) R(g) + S(g) At equilibrium, the partial pressures are PA= 0.30 atm, PB= 0.70 atm, PR= 0.25 atm, and PS= 0.15 atm at 300. K. a) Calculate the equilibrium constants Kcand Kpat 300 K. b) How is the equilibrium affected if additional R is added to the system? c) How is the equilibrium affected if the total pressure of the system is doubled at constant temperature?
