Answer: If a reaction releases 675,000 Joules then it means it releases 161.328872 kcal.
Explanation:
According to the standard conversion,
[tex]1 Joule = 0.000239006 kcal[/tex]
Therefore, 675,000 Joules will be converted into kcal as follows.
[tex]1 Joule = 0.000239006 kcal\\675,000 J = 675000 J \times \frac{0.000239006 kcal}{1 J}\\= 161.328872 kcal[/tex]
Thus, we can conclude that if a reaction releases 675,000 Joules then it means it releases 161.328872 kcal.
