For the reaction, 4 A(g) + 3 B(g) => 2 C(g), the following data were obtained at constant temperature.
Experiment Initial A, mol/L Initial B, mol/L Initial Rate, M/min
1 0.200 0.150 5.00
2 0.400 0.150 10.0
3 0.200 0.300 20.0
4 0.400 0.300 40.0
1. Determine the value of k for the reaction.
2. Which of the following is the correct rate law for the reaction?1. Rate = k[A]2[B]22. Rate = k[A][B]3. Rate = k[A]2[B]4. Rate = k[A][B]2

How many molecules are found in 1.32 mol of nacl?

Answer asap need by wednesday morning explain how a buffer works, using an ethanoic acid/sodium ethanoate system including how the system resists changes in ph upon addition of a small amount of base and upon addition of a small amount of acid respectively. include the following calculations in your i. calculate the ph of a solution made by mixing 25cm3 0.1m ch3cooh and 40cm3 0.1m ch3coo-na+. [ka = 1.74 x 10-5 m] ii. calculate the ph following the addition of a 10cm3 portion of 0.08 m naoh to 500cm3 of this buffer solution. iii. calculate the ph following the addition of a 10cm3 portion of 0.08 m hcl to 200cm3 of the original buffer solution.
