Answer:
It increases when the temperature increases.
Explanation:
- According to Arrhenius relation: k = Ae(-Ea/RT).
- The rate constant of the reaction and also the rate of the reaction increases exponentially with increasing the temperature of the reaction.
- As the temperature increases, the no. of molecules that can posses the critical energy (activation energy) to initiate the chemical reaction and pass the energy barrier increases.

Percent error is the difference between the measured and known value, divided by the known value, multiplied by 100%.
So first, we take our measured value, .299 cm, minus our known value, .225 cm.
.299 cm - .225 cm=.004 cm
Next, we divide that by our known value
Finally, multiply your answer by 100
.0177777778 x 100= 1.77777778 %
Round to three significant figures, and you're done.
=1.78 % error
B. False
When the maximum amount of solute has been dissolved in a given amount of solvent, we say that the solution is saturated with solute.
