Question
Chapter 15, Problem 90A
Interpretation Introduction
Interpretation:
The change in enthalpy for the given changes in the system needs to be determined.
Concept introduction:
The enthalpy change of the system alters in accordance to the changes done to the system.
Expert Solution & Answer
Answer to Problem 90A
The value of ?H will be tripled and its sign will be reversed.
Explanation of Solution
Since the amounts of all the substances are tripled, ?H will also be tripled and its sign will change with the change in direction of the reaction.
