Coal, which is primarily carbon, can be converted to natural gas, primarily CH4, by the exothermic reaction: C(s)+2H2(g)CH4(g) Part A Which disturbance(s) will favour CH4 at equilibrium? Check all that apply. adding more C to the reaction mixture adding more H2 to the reaction mixture adding neon gas to the reaction mixture adding a catalyst to the reaction mixture lowering the volume of the reaction mixture raising the temperature of the reaction mixture
