Chemistry

A mixture containing an initial concentration of 0.1726 M for H2and 0.1361 M for I2 is allowed to come to equilibrium (see reactionbelow). What must be the equilibrium concentration of HI? H2(g) +I2(g) â†” 2HI(g) Kc = 48.7000
0.0726 M
0.0582 M
0.1164 M
0.2327 M

changeÂ Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â -aÂ Â Â Â Â Â Â Â Â Â Â Â Â Â Â -aÂ Â Â Â Â Â Â Â Â Â Â Â Â +2a

Equb concÂ Â Â Â Â Â Â 0.1726-aÂ Â Â Â Â Â 0.1361-aÂ Â Â Â Â Â Â 2a

Equilibrium constant , K_c = [HI(g)]² / ([H₂(g)][I₂(g)] )

K_c = 48.7000 = (2a)² / [(0.1726-a)(0.1361-a)]

Solving we get a = 0.1164M

Therefore the equilibrium concentration of HI = 2a
