please help me with this

1. Given following reaction: H298.S(Jmole1)S298(JK1mole1)N2(k)+3H2(k)191,49130,592NH3(k)46190192,51 2. Calculate S,G and Kp of reaction at 298K. 2. If p1=0,5atm,pn+=0,1atm,pmn=1,0atm what direction is spontaneous at 298K ? 2. Given following reaction: MgCO3(r)MgO(r)+CO2(k) And thermodynamics data: 1. Calculate H,S and G of reaction at 298K, what direction is spontaneous at 298K ? 2. What temparature which starting of decomposition MgCO3(r) t standard condition? Assume H,S is constant with
