Hi This is a general assumption and a valid one. Increasing the temperature of the reactants will increase the possibilty of the reaction taking place. But there are other factors. Thermodynamics provide an "end point" but it does noe mean that that "end point" will take palce in reasonable time or that it will take place at all. Increasing the temperature will certainly increase the entropy of the system and such an increase may be enough to decrease the Free energy, but any issue to consider is the possibility of decomposition of the reactant with increase in temperature and other side reactions. This is why increasing the temperature may not be the appropriate way of opushing a reaction to the "right". One time- honoured was is the use of catalysts. This particular reaction leads to the dissolution of I2 into water resulting in idodide anions. HI is a strong electrolyte which will "prefer" to be in its dissociated form, unless one is looking at the reaction in the gas phase, and under pressure where the possibility of HI as a gas is a real one.
