An organism uses the following reaction to generate free ene

An organism uses the following reaction to generate free energy: CH_4 + SO_4^2- + 2H^+ rightarrow H_2S + CO_2 + 2H_2O which of the following would increase the amount of free energy available to this organism? There is more than one correct answer, select all that apply to receive credit. The CH_4 concentration were to decrease The SO_4^2- were to decrease The CO_2 were to increase The CH_4 concentration were to increase. The H_2S concentration were to go down. The pH were to decrease

Solution

the free energy in organisms is either produced by photosythesis or cellular respiration in which hygrogen and oxyhen must be in 2:3 ratio (basic assumption).
