Gaseous indium dihydride is formed from the elements at elevated temperature: In(g)+H2(g)⇌InH2(g),Kp=1.48 at 973 K The partial pressures measured in a reaction vessel are PInPH2PInH2===0.0550atm0.0290atm0.0780atm Determine the equilibrium partial pressure of In. Determine the equilibrium partial pressure of H2. Determine the equilibrium partial pressure of InH2.

Expert Solution

In(g) + H2(g) ⇌ InH2(g

I 0.055 0.029 0.078

C +x +x -x

E 0.055+x 0.029+x 0.078-x

Kp = P_InH2/P_In P_H2

1.48 = 0.078-x/(0.055+x)(0.029+x)

1.48*(0.055+x)(0.029+x) = 0.078-x

x = 0.062

P_In = 0.055+x = 0.055+0.062 =0.117atm

P_H2 = 0.029+x = 0.029+0.062 = 0.091atm

P_InH2 = 0.078-x = 0.078-0.062 = 0.016atm

Find the temperature in ºC at which Kp = 43.7 for the reaction H2(g) + I2(g) ⇌ 2 HI(g). Use ∆Hºrxn and ∆Sºrxn to calculate and assume that they are independent of temperature. Use the thermodynamic data in the appendix of your textbook; I have provided the needed appendix on BlackBoard for your convenience. Report your answer to zero places past the decimal.
