for the following reaction, the change in enthalpy under the standard conditions at 25 C is -184.6. H2(g) + Cl2(g) -> 2Hcl. what is the enthalpy of formation of hcl
Homework Answers
When 2 moles of HCl is formed, enthalphy is -184.6
Enthalphy of formation is defined when 1 mol of Hcl is formed
when 1 mol of Hcl is formed, enthalphy will be -184.6/2 =92.3
Ans: -92.3
