Question

The rate constant that you calculated is called pseudo-first order because besides the tert-butyl chloride concentration the rate of the reaction also depends on all except which factor?

Select one:

a. the solvent

b. the tert-butyl alcohol concentration

c. the temperature

d. the time of year

e. the acid concentration

To mitigate the effect of other factors besides tert-butyl chloride concentation on the rate of the reaction, we did all except which?

Select one:

a. keep the reaction at a constant temperature

b. run the reaction with a high tert-butyl chloride to solvent ration

c. run the reaction with a low tert-butyl chloride to solvent ratio

Explanation / Answer

1. The rate constant that you calculated is called pseudo-first order because besides the tert-butyl chloride concentration the rate of the reaction also depends on all except which factor?

Select one: d. the time of year      (This is not a criteria in which year we did this, any time we can do this experiment)

2. To mitigate the effect of other factors besides tert-butyl chloride concentation on the rate of the reaction, we did all except which?

Select one: c. run the reaction with a low tert-butyl chloride to solvent ratio    (From above question we found that rate depends on the tert-butyl alcohol concentration)

This is in accordance with Lechatlier's Principle, which states that increasing reactants concentrations or decreasing products concentration will lead to shift the equilibrium towards right-side (Product side).
