please help with part 3 all parts- imp

Co(H2O)62(aq)+4Cl(aq)CoCl2(aq)+6H2O(l)pinkblue Based on your observations, in which direction does the equilibrium shift (left or right?): (1 mark) when heated from 50C to approximately 100C let when cooled from 100C to approximately 0C Based on your answers to the question 6 above, decide whether the equilibrium is exothermic (H0). Explain your choice clearly. ( 2 marks) Write an expression for the equilibrium constant, K6, for the above reaction. (1 mark) When the temperature is increased, what happens to the value of K (does it increase, decrease, or stay the same)? Explain.
