Question

Assertion (A) : Molarity of a solution in liquid state change with temperature.

Reason (R) : The volume of a solution changes with change in temperature.

(a) Both A and R are true and R is the correct explanation of A.

(b) Both A and R are true but R is not the correct explanation of A.

(c) A is true but R is false.

(d) A is false but R is true.

Answer 1

(a) Both A and R are true and R is the correct explanation of A.

Assertion and Reason are correct statements and Reason is the correct explanation of Assertion. Volume of solutions is a function of temperature which varies with temperature. Hence, molarity of a solution in liquid state change with temperature

Molarity = Moles of solute / Volume of solution (in L)
