Consider the intermediate chemical equations. CH sub 4 times g plus 2 cap o sub 2 g rightarrow CO sub 2 times g plus 2 cap h sub 2 cap o g triangle cap h sub 1 is equal to negative 802 kJ 2 cap h sub 2 cap o g rightarrow 2 cap h sub 2 cap o l triangle cap h sub 2 is equal to negative 88 kJ The overall chemical reaction is shown. CH sub 4 times g plus 2 cap o sub 2 g rightarrow CO sub 2 times g plus 2 cap h sub 2 cap o l triangle cap h sub 2 is equal to negative 890 kJ What is the correct enthalpy diagram using the Hess law for this system?

Question

Revolt · Accepted Answer

Image with description An enthalpy diagram has 3 arrows. The top line is labeled as C H subscript 4 g plus 2 O subscript 2 g, the baseline is labeled as C O subscript 2 g plus 2 H subscript 2 O g, and the new lower baseline is labeled as C O subscript 2 g plus 2 H subscript 2 O l. Arrow 1, points down from the top line to the baseline and is labeled as negative 802 kilo Joule. Arrow 2, continues pointing downward from arrow 1; it meets a horizontal new lower baseline and is labeled as negative 88 kilo Joule. Arrow 3, points down from the top line, past the baseline to a new lower baseline, and is labeled as negative 890 kilo Joule.
