Directions : In the following question more than one of the answers given may be correct. Select the correct answer and mark it according to the code:
The enthalpy change for the process \[C(graphite)\xrightarrow{{}}C(g)\]is called: (1) heat of vaporisation (2) heat of sublimation (3) heat of atomisation (4) heat of allotropic changeA) 1, 2 and 3 are correct
B) 1 and 2 are correct
C) 2 and 4 are correct
D) 1 and 3 are correct
Correct Answer: C
Solution :
\[C(graphite)\xrightarrow{{}}C(g)\] In this process sublimation as well as allotropic change is occurred hence, the enthalpy change for this process is called heat of sublimation as well as heat of allotropic change.
