Hydrogen iodide is added to an evacuated reaction vessel. The vessel is sealed and warmed. A
decomposition reaction occurs. Hydrogen and iodine are formed. Some hydrogen iodide remains.
When equilibrium is established, the total pressure is $1.20 \times {10^5}Pa$. The partial pressure of hydrogen is $4.00 \times {10^3}Pa$.
Hydrogen iodide, hydrogen and iodine are all gaseous under the conditions used.
What is the value of ${K_p}$…
