are there standard rates of formation?

Postby Payton Kammerer 2B » Sat Mar 14, 2020 8:24 pm

For H, S, and G, we used standard values of formation for different compounds at particular temperatures and pressures. Does anything similar apply to rates? For example, it takes this long to form 1 mol of H2 from 2 mol of H under standard conditions, and then you can use that value in conjunction with a reaction mechanism to predict a specific rate constant for the overall reaction? And then, within each step, you might even be able to figure out which bond is limiting, like, taking the longest time to break or form out of all the bonds altered in that step?

most likely for the test we will be given that information, not required to look it up from a chart ourselves.

They should give you this information in the question or somewhere on the test. It would definitely be tedious if we had to look these up by ourselves.

How would you apply this kind of standard rate to a test problem? Arrhenius equation is one thing i can think of, but are there others?

They will be given because the person he had take the test to test it out took it closed book.
