Formulas on test?

Postby Nahal 1F » Wed Mar 07, 2018 1:00 pm

Does this week's test include the 1st order and 2nd order formulas and the half-life formulas or do we have to memorize them?

No, you won't have to memorize the equations. The constants and equations sheet has all of the necessary 1st order and 2nd order formulas and the half-life formulas that you will need on the test. However, they are not labeled as 0, 1st, or 2nd order, so you will have to recognize which equation applies to the order given the problem at hand.

Those formulas are on the formula sheet! You can see that sheet on Lavelle's website under "Constants and Equations"

The equations sheet including the integrated rate laws and half lives were given on the test. However, the equations are not indicated as 0th, 1st, or 2nd order so you'd still have to be able to identify them on the sheet.
