Options

  1. AA cylindrical vessel with a diameter of 12 cm holds 800π cm^3 of water. A cylindrical glass piece having a diameter of
  2. BA cylindrical vessel with a diameter of 12 cm holds 800π cm^3 of water. A cylindrical glass piece having a diameter of
  3. CA cylindrical vessel with a diameter of 12 cm holds 800π cm^3 of water. A cylindrical glass piece having a diameter of
  4. DA cylindrical vessel with a diameter of 12 cm holds 800π cm^3 of water. A cylindrical glass piece having a diameter of

Correct answer

B. A cylindrical vessel with a diameter of 12 cm holds 800π cm^3 of water. A cylindrical glass piece having a diameter of

Step-by-step solution

Only option (B) is exothermic. Rest all options are endothermic.

For a reaction A → B, enthalpy of reaction is - 4 . 2kJ mol ^ - 1 and enthalpy of activation is 9 . 6kJ mol ^ - 1 . The
