Equilbria tgb x C The Following Equilibriu X Secure https://www.webassignet web/Student Assignment Responsesiastdep-17769542.02 11.5 points 1 15 EX.010 Consider the following equilibrium at 990. K. Hz(g) + 12(g) 2 HI(g); Kp 43.2 Suppose this reaction is started with 0.334 atm H2 and 0.375 atm 12 at the same temperature. Assume the initial partial pressure of product is equal to o (a) Is the system at equilbrium? If not, in which direction will the reaction shift to reach equilibrium? The system :-Select-T at equilibrium and -Select- (b) Calculate the equilibrium partial pressures of each reaction component. atm atm atm

Explanation / Answer

system is not at equilibrium, the system shift to right to reach equilibrium.

           H2(g)   +   I2(g)   <---->   2HI(g)

initial 0.334 atm     0.375 atm          0

change    - x           -x               +2x

equil   0.334-x       0.375-x             2x

Kc = [HI]^2/[H2][I2]

43.2 = (2X)^2/((0.334-X)(0.375-X))

X = 0.27

AT equilibrium,

pH2 = 0.334-0.27 = 0.064 atm

pI2 = 0.375 - 0.27 = 0.105 atm

pHI = 2*0.27 = 0.54 atm
