Question
Part A: calculate delta H for the reaction between hydrogen and Cl2. Part B: calculate delta S for the reaction between hydrogen and Cl2. Part C: calculate delta G for the reaction between hydrogen and Cl2. Part D: calculate Kp for the reaction between hydrogen and Cl2. -I have no idea how to do this H2 reacts with the halogens (X2) according to the reaction: 112(g) + X2(g) 211x(g) where Xz can be Cl2 Brz or I Reactant/Product Al (kJ/mol)As (J/mol K) ASf (J/mol K) 130.7 223.1 186.9 245.5 198.7 260.89 206.8 H2(9) H2(a) Cl2(9) 0 0 92.3 30.9 -36 3 82 42 28 5 HCI(g) Br2(g) HBr(g) I209) HI(g) 208Explanation / Answer
H2+Cl2 ---->2 hcL
DHrxn = 2*DHf0hcL-(DHf0H2 + DHf0Cl2)
= 2*-92.3 -0
= -184.6 kj
DS0rxn = 2*DSf0hcL-(DSf0H2 + DSf0Cl2)
= (2*186.9)-(130.7+223.1)
= 20 j/mol.k
DG = DH-TDS
if T = 298 k
= (-184.6*10^3)-(298*20)
= -190.56 kj
DG = -RTlnK
-190.56*10^3 = - 8.314*298lnk
k = 2.53*10^33
