Consider the equilibrium CH4(g)+4 I2(s)CI4(g)+4 HI(g).

(a) If the partial pressure of CH4 is increased, what happens to the partial pressure of CI4?

(b) If the partial pressure of CI4 is decreased, what happens to the amount of I2?

(c) If the concentration of HI is increased, what happens to the equilibrium constant for the reaction?

(d) If the amount of I2 is increased, what happens to the concentration of

(this is how it is asked on the book)
