Equilibrium mole

The following reaction reaches equilibrium at the specified conditions.C6H5CH = CH2(g) + H2(g) = C6H5C2H5(g)The system initially contains 3 mol H2 for each mole of styrene. Assume ideal gases. For styrene, deltaGnought of fluid @298 = 213.18 kJ/mol.deltaHnought of fluid @ 298 = 147.36 kJ/mol.a) What is Ka (K sub a) at 600 degrees Celsius?b) What are the equilibrium mole fractions at 600 degree C and 1 bar?c) What are the equilibrium mole fractions at 600 degree C and 2 bar?The Reaction System is represented byC6H5CH = CH2(g) + H2(g) = C6H5C2H5(g)1301-x(1-x/4-x) P 3-x( 3-x/4-x) P x = 1-x+3-x+x=(4-x) (x/4-x)P Now ?G0 reaction[I Suppose pls write properly ] at…
