This video outlines the procedures for calculating the activation energy of a reaction using Excel. By determining the slope of the best fit line for natural log (ln) of the rate constant (k) versus reciprocal temperature (1/T), the activation energy can be determined.
Flour is the most common mis-measured ingredient. When measuring flour, use the âspoon & levelâ method. Do not scoop the flour out of the container/bag with your measuring cup. Believe me, I catch myself doing it often! Scoop the flour and you could end up with 150% of the correct measurement. Rather, using a spoon, scoop the flour into the measuring cup. Do not pack the flour down and do not tap the measuring cupâ both cause the flour to settle in the cup. After youâve spooned the flour into the measuring cup, use the back of a knife to level off the top of the measuring cup.

Dry measuring cups are meant to be filled to the top so that you can shake off the excess and Liquid measuring cups have a spout which is used for pouring hot and liquid stuff. Measuring 1 cup of flour in a dry measuring spoon will be more convenient, simply fill it to the top and easily level off using a knife. On the other hand using a liquid measuring cup as a replacement would mess up the whole recipe.
