Interpretation: The heat change for the formation of ethane is to be calculated.
Concept Introduction: Hess’s law states that the overall change in enthalpy for the solution is the sum of all changes independent of the different phases or steps of a reaction.
Answer to Problem 95A
The heat change for the formation of ethane from ethene and hydrogen is
Explanation of Solution
The
The thermochemical equations given are
To get the required chemical reaction, first, we have to reverse the reaction
Now we have to multiply the reaction
Now, add the two reactions
Now we have to divide the reaction
