What will happen If CH4 is added to the following reaction at equilibrium CH4 (g) + 2H2O (g) <------> 3H2 (g) + CO2 (g)
1. reaction will shift to the the right and the concentration of CO2(g) will decrease
2. reaction will shift to the the right and the concentration of CO2(g) will increase
3. reaction will shift to the the left and the concentration of CO2(g) will decrease
4. reaction will shift to the the left and the concentration of CO2(g) will increase
