In any nuclear reaction, energy is released or absorbed and accordingly the Q-value which is our index for the change in the energy is positive or negative. Study the statements given below and identify the correct one(*).
i. In the exoergic reaction Q is positive Energy is released
ii. In the exoergic reaction Q is negative Energy is absorbed
iii. In the endoergic reaction Q is negative Energy is absorbed
iv. In the endoergic reaction Q is positive Energy is released
(1) i and iii
(2) i and iv
(3) ii and iv
(4) i only
