e net ionic reaction is; Zn(s) + 2H,O*(aq) → Zn²*(aq) + H,(g) drochloric acid is a strong acid and acetic acid is a weak acid. Based on the above information, explain th the two reaction rates.

How long will it take for the concentration of A to decrease from 0.850 M to 0.205 for the reaction A → Products? (k = 0.0882 M⁻¹s⁻¹)

1. Below are the data for the decomposition of P2O5.  t., minutes    [P2O5]      1.25 0.852 6.52 0.721 12.22 0.602 17.90 0.501   (a) Determine the value of k for the reaction (be sure to include units). (b) What will the concentration of [P2O5] be at 28.50 minutes?  (You will need to use the value of k and the integrated rate law.) (c)  How long must the reaction proceed until [P2O5] is 0.111 M?

The pH change during a reaction will be followed by inserting a pH probe into a relatively small volume of liquid sample,  At least 1.5 cm of the pH probe must be immersed in the reaction solution. What is the best choice of reaction vessel for this reaction?      a volumetric flask      a Berzelius beaker      a Griffin beaker      a round bottomed flask      an Erlenmeyer flask

How long will it take for the concentration of A to decrease from 0.850 M to 0.271 for the reaction A → Products? (k = 0.0882 M⁻¹s⁻¹)

Which of the reactions that do not occur can be made to occur if an acid catalyst is added to the reaction mixture?

At 40^0c, H202 (aq) will decompose according to the foll. reaction: 2 H202 (aq) ----2H20(l) +02 (g) The foll. data were collected for the concentration of h202 at various times. Time.                    [H202] (mol/L) 0.                           1.600 3.10*10^4              0.592 6.20*10^4.            0.219 (a) Calculate the average rate of decomposition in H202 between0 and 3.10 * 10^4 s. use this rate to calculate the average rate of production 02 (g) over the same time period. (b) What are these rates for the time period 3.10*10^4 s. to 6.20 *10^4 s.? Rate of H202 decomposition Rate of O2 Production

topic: molecular collision reactions A student reacts ground chalk, CaCO3(s), with HCl(aq) in an open beaker at room temperature. Explain, using collision theory, what happens to the rate of the reaction as the reaction proceeds to completion.

How do I calculate k when [X]= .42 M and the rate of reaction is .0030 M/s. I can't remember exactly how to do this type of problem. Thank you for the help !
