Question

The reaction between gaseous Hydrogen and Chlorine is

H↓2+ Cl↓2→ 2; ΔHCl H0r = -184K

(i) What is the enthalpy of formation of HCl?

(ii) How much heat will be liberated at 298K and 1 atm for the formation of 365 g

of HCl?

Answer 1

Answer:

Hydrogen chloride may be formed by the direct combination of chlorine (Cl2) gas and hydrogen (H2) gas; the reaction is rapid at temperatures above 250 °C (482 °F). The reaction, represented by the equation H2 + Cl2 → 2HCl, is accompanied by evolution of heat and appears to be accelerated by moisture
