I NEED HELP WITH THIS PROBLEM SOMEONE HELP PLEASE!!! Consider the following reaction at equilibrium. What effect will decreasing the temperature have on the system? CO2(g) + 2 H20(I) = CH4(g) + 2 - AH° - +890 kJ O2(g) No effect will be observed. The reaction will shift to the right in the direction of products. The equilibrium constant will increase. The reaction will shift to the left in the direction of reactants.
can someone please answer as well as explain why? Thank you. I also need clarification on what makes a molecule have a partial negative charge.
