Anaerobic digestion of volatile acids by methane bacteria is represented by the equation:

                                   

The composition of methane bacteria is approximated by the empirical formula CH1.4Oo.40N0.20. For each kg acetic acid consumed, 0.67 kg CO 2 is evolved. How does the yield of methane under these conditions compare with the maximum possible yield?

Precision will be reduced, but yield will be increased
Optimisation of a PCR reaction is often a compromise between the competing demands for precision, efficiency and yield. Although the specific effects may vary, generally, increasing the annealing temperature will increase non-specific primer binding and reduce precision. Increasing the length of the elongation phase will reduce the proportion of incomplete newly-synthesised strands and therefore increase yield. In this case, the potential effect on efficiency is unclear. Increasing the elongation phase would increase the reaction time, but the time taken to ramp down to a lower annealing temperature would be reduced.
