A waste with a concentration of 0.1 gram per liter is to be introduced to a hazardous waste reactor that is to achieve 90% destruction. A reactant, which is intended to cause an exothermic reaction is to be mixed with the waste stream so that there is only one common/mixed input to the reactor.
If the waste is in excess of the reactant and is modeled with 1st order kinetics equal to k=1000/minute --- what does this mean?
And if the reactant was in excess to the waste stream and was modeled with 2nd order kinetics equal to k = 1000 g-moles per liter minute --- what does this mean?
What is the simple difference between the first and second order kinetics? Is there a benefit to one process over the other?© BrainMass Inc. brainmass.com October 24, 2018, 9:04 pm ad1c9bdddf
Let W be the concentration of the waste
R be the concentration of the reactant
P be the product
We can write the general reaction as below:
W + R = P
Here we're not given the reaction stoichiometry, i.e. how much W will react with how much R. Therefore it is normal in chemistry that a number of assumptions and predictions are made.
First, the waste is in excess of the reactant and is modeled with 1st order ...

Hydrating power of water, Gatorade and PowerAde.
A register dietitian has been asked to help the lawyers decide which hydrating product (water, Gatorade, or PowerAde) is best for them. She needs to do a presentation that explains the pros and cons takeing into consideration the effect on their health and overall wellness.
For most of your life you have been drinking water and/or some water based drink. You could easily name your favorite beverage brand. We know water is natural and therefore (probably) good for us. Are these other products good for us? Whose studies should we believe? What is their proof? Let's explore by comparing labels, information, and marketing strategies!
You are a Registered Dietitian, and you have been invited to a Lunch and Learn program at a very large law firm. The firm must make a decision about which company they will select for a year long beverage contract. The lawyers must choose water, Gatorade, or Powerade. Of the 55 attorneys attending your presentation, 32 of them workout regularly for 1 hour five days out of the week.
The title of your presentation is: "Water: An Overlooked Essential Nutrient." The firm has requested that you address all of the questions mentioned in the introductory paragraph while creating a handout that compares water, Gatorade, and Powerade on the following categories:
Advantages of consumption (include research reviews)
Disadvantages of consumption (include research reviews)
