Question
The equilibrium constant, Kc, for the following reaction is
6.93 x 104 at 438 K.
PC15 (9)
PC13 (g) + Cl₂ (9)
When a sufficiently large sample of PC15 (g) is introduced into an
evacuated vessel at 438 K, the equilibrium concentration of C1₂ (g) is
found to be 0.246 M.
Calculate the concentration of PC15 in the equilibrium mixture.
[PC15] =
M

A student ran the following reaction in the laboratory at 650 K:
H₂ (9) + 1₂ (9) 2HI(g)
When she introduced 0.224 moles of H₂ (g) and 0.238 moles of I2 (9)
into a 1.00 liter container, she found the equilibrium concentration of
HI(g) to be 0.368 M.
Calculate the equilibrium constant, K, she obtained for this reaction.
