(a) What is meant by a reversible reaction?

(b) An increase in temperature of the following reversible reaction causes more of the CuSO4 (aq) to be formed. What can be deduced about the enthalpy of the reaction? Explain your deductions.

CuSO4 (aq) <=> CuSO4. 5H2O

Answer:

(a) A reversible reaction is one which can go both forward and backward.

(b) Enthalpy change for the reaction is exothermic. An increase in temperature will thus favour the backward reaction so as to decrease the temperature.
