A student studied the solubility of three substances in water at different temperatures and collected the data given below. (Solubility is expressed as the grams of the solute dissolved in 100gms of water to form a saturated solution).

Answer:
c
Explanation:
for an exothermic process, energy is lost as the product increases.
undissolved solute ⇄ dissolved solute
in this case, if we take forward reaction as exothermic, then that means increase in temperature (energy provided) would result in the process shifting towards the left hand side (application of le chatlier's principle). i.e. less product (dissolved solutes) will be formed while the undissolved solutes increase in amount. which means that solubility should decrease as temperature increases, which is the case in C.
