It is found when an unknown solid solute is dissolved in water that the solubility of the solid increases if temperature is decreased. What can be determined about the entropy and enthalpy of the dissolution of this unknown solid? not enough information to make a determination entropy is increased, exothermic entropy is decreased, exothermic entropy is increased, endothermic entropy is decreased, endothermic

exothermic entropy is increased

Explanation:

An exothermic process is one whose rate increases when the temperature is decreased. Hence if a decrease in temperature favours the dissolution of more solute at equilibrium, then the process is exothermic.

Similarly, the dissolution of a solute in a solvent increases the disorderliness (entropy) of the system because of the increase in the number of particles present. Hence once a solute in dissolved, the entropy of the system increases.

r just means there's a number of carbon in teh chain. for example rcooh means that after x number of carbon, the chain ends with cooh.
