Would you expect the rate constant to change if you heated up the reactants before mixing?...
Would you expect the rate constant to change if you heated up the reactants before mixing? If the rate constant would change, would it be larger or smaller than at room temperature? Why or why not?

5. a) Determine the maximum axial load the member shown can support before you would expect it to yield. The structure is made of A36 steel. The thickness of the structure is 2.0 in., the larger width is 12.0 in., and the smaller width is 8.0in. The fillet radius is 0.5in. b) A 35 ksi axial stress is applied to the beam cyclically (repeatedly applied then removed). How many times can this be done before you would expect the part...

A certain temperature and volume would you expect the pressure
of a given number of moles of KR or CCL4 to deviate more from ideal
behavior? why?
O O O CCI, because it occupies a larger volume and has smaller dispersion forces between molecules. CCl4 because it occupies a smaller volume and has greater dispersion forces between molecules. CCl4 because it occupies a larger volume and has greater dispersion forces between molecules. Kr because it occupies a smaller volume and...

In setting up your 3 kinetics experiment, you will be mixing different volumes the two reactants (oxalic acid (H2C2O4) and potassium permanganate (KMnO4)). If you mix 10 ml of 0.02 M with 20 ml of 0.5 M oxalic acid, what is the concentration of H2C2O4 in the mixture? Hint: Use M1V1 = M2 V2.

2. In the mixing process you analyzed, the inner calorimeter cup started how many degrees below room temperature and ended how many degrees above room temperature? Explain why using water from the water cooler, rather than tap water (or hot water or ice water or water from a bottle in your backpack) is a good choice for an accurate experiment. 3. Suppose that a student stirs the calorimeter very zealously, rather than gently, in step 5. Suppose the student exerts...

(2pts) Post-lab Questions AH Choose. ΔΗ (1pts) 1. Do you expect the solubility of Borax to increase or decrease as temperature increases? Select the option that best explains why. A. Solubility will increase, because as Tincreases the term becomes smaller therefore will get larger. B. Solubility will increase, because as Tincreases the IT term becomes smaller therefore K will get smaller. C. Solubility will decrease, because as increases the term becomes smaller therefore Kwill get smaller. D. Solubility will decrease,...
