Thermodynamics question

2024 · 5 Apr · Shift 1 · Q6

JEE MainChemistryThermodynamicsMCQ+4 / −1
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 kJ mol−1-57 \mathrm{~kJ} \mathrm{~mol}^{-1}−57 kJ mol−1 Reason (R) : Enthalpy of neutralisation is the amount of heat liberated when one mole of H+\mathrm{H}^{+}H+ ions furnished by acid combine with one mole of −OH{ }^{-} \mathrm{OH}−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.
  1. A
    (A) is true but (R) is false
  2. B
    Both (A) and (R) are true and (R) is the correct explanation of (A)
  3. C
    Both (A) and (R) are true but (R) is not the correct explanation of (A)
  4. D
    (A) is false but (R) is true
