We are two sisters on a mission to demystify science with humor and relevance by creating videos, GIFs, comics, and resources. Our content is focused on high school biology (Pinky is a former high school biology teacher), though we do receive comments that some of our content is useful for intro biology courses at the college level as well. We're for anyone wanting to learn biology! We frequently remind viewers that we cannot include all of the fascinating exceptions and details in a video under 10 minutes. We like to create memorable visuals to the content, but they're not scientific illustrations. Meaning, nitrogen and carbon don't tap dance. Our illustrated cell and molecule cartoons are definitely not to scale. DNA is usually a right-handed double helix (well...there are exceptions) and it doesn't have eyes...a face...or a top hat...

Masterpieces of microengineering, kinesins are motorized transport machines that move cellular materials to their correct locations in the cell so they can perform their functions. Kinesins have two feet, or "globular heads," that literally walk, one foot over another. Known as the "workhorses of the cell," kinesins can carry cargo many times their own size.

Comparing initial rates to determine the order of reaction is a very common question in Kinetics.
Let's take a look at an example:
The objective is to choose a pair of experiments for comparison where the concentration of a reactant changes and ideally the concentration of other reactants remain constant. This means that any change in the initial rates of the experiments must be due to the change in the concentration of that reactant, and we can figure out the order from there.
1. Order of Reaction with respect to HCl
Comparing experiments 1 and 3, concentration of HCl doubles and there is no change in concentration of sucrose. So the change in initial rates must be due to HCl only. We can work out the change in initial rates to be 2 times. This means when concentration of HCl doubles, initial rate doubles. Therefore order of the reaction with respect to HCl will be order 1. For comparison, if order of reaction is zero, initial rate will remain unchanged when concentration of HCl doubles. If order of reaction is 2, initial rate will increase by 4 times (2^2 times) when concentration of HCl doubles. Since we only have 3 possible orders to consider, figuring out the order of reaction is quite straightforward.
2. Order of Reaction with respect to sucrose
Comparing experiments 1 and 2, concentration of sucrose increase by 1.5 times and there is no change in concentration of HCl. So the increase in initial rates by 1.5 times must be due to sucrose only. Since this is a proportionate increase, order of reaction with respect to sucrose is also order 1. Finally we can write out the rate equation for this reaction to be: rate = k [HCl][sucrose]
