Question
At an elevated temperature, K, = 4.0 × 10-6 for the reaction 2 HBr(g) = H2(g) + Br2(g). If the initial partial pressures of HBr, H2, and Br2 are 1.0 × 10-2 atm, 2.0 × 10- 3. 4 atm, and 2.0 × 10-4 atm, respectively, what is the equilibrium partial pressure of 6. H2? At 1000 K, Kp = 19.9 for the reaction Fe203(s) + 3 CO(g) = 2 Fe(s) + 3 CO2(g). What is the value of K, for the reaction 4 Fe203(s) + 12 CO(g) = 8 Fe(s) + 12 CO2(g)? Exactly 3.75 moles of N204 is placed in an empty 1.0-L container. After a period of time, equilibrium is reached and described by the equation below: N204 (g) = 2NO2 (g) If at equilibrium the N204 is 45% dissociated, what is the value of the equilibrium constant for the reaction?
