What statement about the catalyst is correct? it increases a value of the equilibrium constant It increases the number of collisions between reacting molecules. It makes the reaction more endothermic. It provides an alternative reaction mechanism with a lower activation energy. It shifts an equilibrium to the right

i See Periodic Table See Hin Increasing the concentration of a reactant shifts the position of chemical equilibrium towards formation of more products. What effect does adding a reactant have on the rates of the forward and reverse reactions? Choose one: O There is no effect on the forward and reverse reactions. For an equilibrium reaction, the forward and reverse rates are always equal. O Both the forward and reverse reactions speed up by the same amount. O The forward reaction speeds up immediately. As more product is made, the reverse reaction starts to speed up as the forward reaction starts to slow down until they are equal. O The forward reaction slows down initially. As the reaction proceeds, the reverse reaction slows down to meet the new forward reaction. O The forward reaction speeds up. Eventually, production of the product speeds up the reverse reaction rate to match the new forward rate. O It is impossible to say without more specific information.
