Answer:

-248.425 kJ/mol

Explanation:

This question can be done by simply taking the ratios:

Since the given the heat change for 1.00 mol of [tex]CO_2[/tex] is -373.7 KJ/mol. Let us consider the required Heat Exchange at 0.631 mol of

We can write:

[tex]\frac{-373.7} {1.00} = \frac{x}{0.631}[/tex]

[tex]x = ( -373.7)(0.631)[/tex]

[tex]x = -248.425[/tex] KJ/mol
