Question

An equilibrium mixture obtained from PCl5(g) <=> PCl3(g) + Cl2(g) has vapour density 80; the calculated value for undissociated PCl5 is 104.25. Select the correct statements.

Accepted Answer

The degree of dissociation is about 0.30

Accepted Answer

The number of moles of gas at equilibrium is about 1.30 per mole of PCl5 taken

Accepted Answer

At the same temperature, the observed vapour density would be higher if the equilibrium were established at a higher total pressure

Answer

The average molar mass of the equilibrium mixture is 80 g/mol

An equilibrium mixture obtained from $PCl X_{5} (g) PCl X_{3} (g) + Cl X_{2} (g)$ has vapour density $80$ ; the calculated value for undissociated $PCl X_{5}$ is $104.25$ . Select the correct statements.
