Given below are two statements : One is labelled as Assertion (A)...
Given below are two statements : One is labelled as Assertion (A) and the other is labelled as Reason (R)
Assertion (A) : Enthalpy of neutralisation of strong monobasic acid with strong monoacidic base is always (-57 \mathrm{~kJ} \mathrm{~mol}^{-1}).
Reason (R) : Enthalpy of neutralisation is the amount of heat liberated when one mole of (\mathrm{H}^{+}) ions furnished by acid combine with one mole of (\mathrm{OH}^{-}) ions furnished by base to form one mole of water.
In the light of the above statements, choose the correct answer from the options given below.
Options
- A(A) is true but (R) is false
- BBoth (A) and (R) are true but (R) is not the correct explanation of (A)
- CBoth (A) and (R) are true and (R) is the correct explanation of (A)
- D(A) is false but (R) is true
Correct answer
C. Both (A) and (R) are true and (R) is the correct explanation of (A)
Step-by-step solution
Enthalpy of neutralization of SA & SB is always because strong monoacid gives one mole of and strong mono base gives one mole of which form one mole of water.
