help me plzzzzz i need at now huhhhuu

5. (I.5 pls). Consider the reaction: H2(g)+Cl2(g)2HCl(g) (a) Calculate H,S,G and K (at 298K) ? Known that: H value of 2HCl(g) is 92kJ/mol and the S value of H2(g),Cl2(g),2HCl(g) is 131J/K.mol,223J/K.mol, and 187J/K.mol, respectively. (b) If H2(g),Cl2(g), and HCl(g) are placed in a flask such that pressure of each gas is I atm, in
