The enthalpy of solution of BaCl₂ (s) and BaC₁₂ 2H_zCXs) are -20.6 and 8.8 kJ mol-I, respectively. The enthalpy change for the reaction is:

Which one of the following statements is false?

State functions depend on a substance's state, such as its amount, type, temperature, or pressure. In actuality, state functions are independent of how the state was created or reached.
State function refers to a set of characteristics that depend only on the initial and final states and not intermediate steps in a reaction or a path. For example, Gibb's free energy.
Heat and work are not functions of the state. Work cannot be the state function because it is proportional to an object's distance moved, determined by the path taken from the initial to the final state. So heat isn't a state function if work isn't.
