Answer to Question #308745 in General Chemistry for Bob

Question

Use the thermochemical equations shown below to determine the enthalpy for this reaction: 2 H₂O_(g) + 2 Cl_2(g) → 4 HCl_(g) + O_2(g) 

ΔH_rxn =   

 

Information:

COCl_2(g) + H₂O_(l) → CH₂Cl_2(l) + O_2(g) 

ΔH = 19 kJ

H₂O(g) →H₂O(l) 

ΔH = -44 kJ

HCl_(g) →1/2 H_2(g) +1/2 Cl_2(g) 

ΔH = 92 kJ

CH₂Cl_2(l) + H_2(g) + 3/2 O_2(g) → COCl_2(g) + 2 H₂O_(l) 

ΔH= -161kJ
