Given the reaction at equilibrium:
X + Y = 2Z + heat
The concentration of the product could be
increased by
A. adding a catalyst
B. adding more heat to the system
C. increasing the concentration of Y
D. decreasing the concentration of X

Many ionic compounds and a few highly polar covalent compounds are because they completely ionize in water to create a solution filled with charged ions that can conduct an electric current.

How does a catalyst increase the speed of a reaction? a. the catalyst eliminates the activated complex stage, allowing products to form immediately. b. the catalyst lowers the energy level of the reactants, making it easier for them to react. c. the catalyst makes it easier for the activated complex to form, lowering the activation energy. d. the catalyst raises the energy level of the products, making the reaction finish sooner. reset next
