Explanation / Answer

from the given data

KP = pH2*pS/pH2S

0.773 = X^2/(0.248-X)

X = 0.197 bar

at equilibrium

partial pressure of H2 = pH2 = 0.197 bar

partial pressure of S = pS = 0.197 bar

partial pressure of H2s = pH2s = 0.248-0.197 = 0.051 bar

total pressure at equilibrium = pH2+pS+pH2S

   = 0.197+0.197+0.051

   = 0.445 bar
