- Q: Consider the decomposition of hydrogen peroxide, shown below. 2H2O20) 2H2O) O2(9) + A) This is an exothermic reaction. Is heat a product or reactant? Write the word "heat" on the appropriate side of the equation. B) Suppose the reaction has reached equilibrium, and you want to produce more product. Suggest two different ways you can shift the equilibrium to the right. C) You may have suggested cooling the reaction down, thereby removing heat (a product) and shifting the equilibrium to the right. However, removing heat will also slow the rate of the reaction. While this will eventually produce more products, it will do it too slowly. How can you still cool the reaction to shift the equilibrium, but also maintain the same rate it had at a higher temperature? 16 étvarrow_forwardFor a reversible reaction, Kp = 23 and Q = 11. Which statement does not accurately describe this reaction at this moment? Question options: The reverse reaction rate is faster than the forward reaction rate. The reaction is not at equilibrium. The concentrations of the products will be higher at equilibrium than they are now.
