Consider the combustion of methane ( as represented by the following equation). This is the reaction that occurs for a bunsen burner, which is a source of heat for chemical reactions in the laboratory. CH4(g) + 2O(g) <--> CO2(g) + 2H2O (g); for the system at equilibrium, which of the following explains what happens to theequilibrium position and K if the tempature is raised?
