Question
Chemistry Question on Thermodynamics terms
The enthalpies of all elements in their standard states are:
A
unity
B
zero
C
0
D
different for each element
Answer
zero
Explanation
Solution
Through conversion, the standard enthalpy of formation (ΔfH+) for an element in its reference state specifically, in its most stable state of aggregation is considered as zero in relation to this standard state. The enthalpy for other compounds is then determined accordingly.
Therefore, the correct option is (B): zero
