Hello! I'm a tad confused about this question. What would be the correct answer?
Consider this reaction at equilibrium: 2 H2O2(g) = 2 H20(g) + O2(g) AH°rxn = -210 kJ/mol Which of the following disturbances will cause the reaction to shift to produce more O2(g)? (Select all that apply.) Volume of the container is reduced at constant temperature. The temperature is decreased. The temperature is increased. The partial pressure of H20(g) is decreased. Volume of the container is expanded at constant temperature. The partial pressure of H2O2(g) is increased. O O

What is the effect of equilibrium when heat is removed (cooled) from the system? CO + H2O ⟷ CO2 + H2 ΔH = +41.4 kJ Group of answer choices Neither reactant nor products would be produced. Shift left. Both reactants and products would be produced. Shift right. This equation does not represent an equilibrium system.
