many variables must be held constant during this kinetics experiment but maintaining a constant temperature is most important. Why?

Expert Solution

many variables must be held constant during this kinetics experiment but maintaining a constant temperature is most important.

Because to calculate the dependence of reaction rate on the reactant concentrations we have to apply the Laws of Mass action ro the reactions and that

At a constant temperature, the rate of a chemical reaction is directly proportional to the product of the concentrations of the reactants.

aA + bB + . . . ® . . .

V = k _* [A]^a_* [B]^b_* . . .

The value of the rate constant k depends on the nature of the reactant, on the temperature, and on the presence of catalysts, but does not depend on the concentration of the substances.

So Without maintaing the constant temperture the rate of the chemical reaction cannot be calculated.

and also with every 10⁰C rise in temperture of the reaction the reaction rate increase 2-4 times of its original Value

So maintaining the constant temperture is the most important part of the Kinetics experiment

Maintaining traceability during requirements and subsequent activities is expensive, because of the addition information that must be captured and maintained. The followings four are the benefits of traceability that outweigh this overhead. 1. Ability to show that all requirements have been implemented. 2. Ability to show that all features in the system correspond to a requirement. 3. Ability to assess the impact of a change. 4. Ability to track the human source of a requirement. Which of those benefits are...

During the experiment a constant tensile load was applied to the sample, as described in Study session 17.1. This caused the sample to extend. You measured the change in length of the sample over time, which enabled you to calculate the strain. In Question 2a you are asked to calculate the stress acting on parts of a sample at the beginning and end of an experiment similar to that in Week 17. The load applied in the experiment was 5.1...
