Problem Which equation represents the average bond enthalpy of a C—H bond?
a. CH 4 ( g ) → C ( s ) + 2 H 2 ( g ) \text{CH}_4(\text{g}) \rightarrow \text{C}(\text{s}) + 2\text{H}_2(\text{g}) CH 4 ( g ) → C ( s ) + 2 H 2 ( g ) CH 4 ( g ) → C ( g ) + 4 H ( g ) \text{CH}_4(\text{g}) \rightarrow \text{C}(\text{g}) + 4\text{H}(\text{g}) CH 4 ( g ) → C ( g ) + 4 H ( g ) 1 4 CH 4 ( g ) → 1 4 C ( g ) + H ( g ) \frac{1}{4}\text{CH}_4(\text{g}) \rightarrow \frac{1}{4}\text{C}(\text{g}) + \text{H}(\text{g}) 4 1 CH 4 ( g ) → 4 1 C ( g ) + H ( g ) 1 4 CH 4 ( g ) → 1 4 C ( s ) + 1 2 H 2 ( g ) \frac{1}{4}\text{CH}_4(\text{g}) \rightarrow \frac{1}{4}\text{C}(\text{s}) + \frac{1}{2}\text{H}_2(\text{g}) 4 1 CH 4 ( g ) → 4 1 C ( s ) + 2 1 H 2 ( g ) Browse the problem library
