Q106

The total change in the enthalpy of a system is independent of the

A.
Number of intermediate chemical reactions involved
Answer
B.
Pressure and temperature
C.
State of combination and aggregation in the beginning and at the end of the reaction
D.
None of these

Answer: Option A

Solution

Answer: Option A
Solution:
The enthalpy is an state variable (point function) so, the change in enthalpy doesn’t depend upon the path involved to bring that change so we can say enthalpy change doesn’t depend upon whether the reaction carried through a path of single step or multiple steps.
