Explain how the rate of diffusion of a gas is related to its molar mass. Carbon dioxide gas (co2) defuse 3.2 times faster than an unknown gas. Determine the molar mass of the unknown gas. Show your work to explain your answer, giving specific values used to determine the answer.

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
