Please help me with chemistry homework This requires the ideal gas laws to solve. Students at a high school in Brekenridge, CO carry out a similar procedure with a larger eudiometer containing 943.5mL of hydrogen gas with known mass of 0.06g at 22 degrees Celsius. Calculate the atmospheric pressure or atm where they live?* Assume the water level inside and outside of the eudiometer are the same just as we assumed in the lab.

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
