does this make any sense at all ? im so stressed out by this, pls someone verify it, its GCSE level... ANALYSIS Apart from propanol, the graph shows the increase of energy output is proportional to the increase of RMM for alcohol. According to the line of best fit, butanol produced the highest amount of energy output. However, without looking at the line of best fit, it states that propanol produces the highest amount of energy output, and this does not support my findings. I will discuss this in the evaluation section. With reference from the above calculations, it was shown that the above analysis agrees to the fact that the energy released followed the order that methanol to ethanol to propanol to butanol. When comparing my predicted results to the actual results from the experiment I have noticed that my results form the experiment were much lower, this could be because of the huge amount of heat energy released into the air. I know from my research that C=O bonds have the highest bond energy of 805, these bonds in butanol were not broken therefore the overall energy output was so low. In the first place, ample of heat energy (that is more than 805 kJ) will have to be made before the bonds are broken as they are so hard to break due to the fact that they have strong double bonds. The gradient of the line is quite steep. There are plenty of spaces in between the points. This must mean that more alcohols can be experimented for to produce a more accurate line of best fit. The general trend of the graph is that the more bonds of an alcohol will guarantee a higher energy output, especially when most of the bonds are C=O bonds. - basicly, i would like to know whether if all the alcohols (methanol,ethanol,butanol,propanol) have the highest bond of C=O, its bond energy is 805J.
