Q. No.Find the correct relationship between the magnitudes of heat evolved (x and y) in the following reactions.
Reaction (i):
C(g) + 4H(g) → CH₄(g)
Magnitude of heat evolved = x kJ mol⁻¹
Reaction (ii):
C(graphite) + 2H₂(g) → CH₄(g)
Magnitude of heat evolved = y kJ mol⁻¹
| 1. | x = y | 2. | x = 2y |
| 3. | x > y | 4. | x < y |

Hints
Given below are two statements:
| Assertion (A): | The heat absorbed during the isothermal expansion of an ideal gas against a vacuum is zero. |
| Reason (R): | The volume occupied by the molecules of an ideal gas is zero. |
| 1. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
| 2. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |
| 3. | (A) is True but (R) is False. |
| 4. | (A) is False but (R) is True. |
