(d) Is the groundwater sample described in part (a) at equilibrium with respect to transformations between CrO4? and Cr2O7²-? If not, which species of Cr(VI) will increase in concentration as the water proceeds towards equilibrium? (The groundwater has ionic strength of 10 mM and pH 8). (e) What is the answer to part (d) if the groundwater temperature was 8°C? Explain your answer by showing how the temperature will change the value for the equilibrium constant K.

I am not sure how to calculate part d and part e.
What does it mean by "as the water proceeds towards equilibrium?" How am I supposed to know which chemical species concentration is increased? Thank you.
