Consider the following reaction: 2NiO(s)→2Ni(s)+O2(g)
If O2 is collected over water at 40.0 ∘C and a total pressure of 747 mmHg , what volume of gas will be collected for the complete reaction of 24.45 g of NiO?

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
