99 Percentile Qs Bank for JEE MainChemistryChemical Equilibrium
Assertion (A) : For an endothermic dissolution process, increase in temperature increases the solubility in a nearly saturated solution. Reason (R) : In saturated solution dynamic equilibrium exists between dissolved solute and undissolved solute.
Options
- ABoth (A) and (R) are correct and R is the correct explanation of A
- BBoth (A) and (R) are correct, but R is not the correct explanation of A
- C(A) is correct but (R) is not correct
- D(A) is incorrect but (R) is correct
Correct answer
B. Both (A) and (R) are correct, but R is not the correct explanation of A
Step-by-step solution
Increase in temperature in an endothermic resolution process enhance the kinetic energy of the solvent molecules by allowing them to break apart more efficiently. This results into the more solubility of solute molecules.
