Consider the following reaction at equilibrium. What effect will doubling the temperature have on the system? CH4 ( + 2 02 () = CO2 (g) + 2 H2O () AH° = -882.0 kJ O No shift will occur because the volume of the system has not changed. No shift will occur because the total number of gas molecules on both sides of the chemical equation are equal. O A shift left towards reactants will occur. O No shift will occur because none of the concentrations have changed. O A shift right towards products will occur.
