The rate of the reaction A + B ___> C + D
Was determined in the experiments at 225 OC. The results are:

Experiment [ A ](M) [B ](M) Initial Rate MS-1
1 0.263 0.826 1.44 x10^-5
2 0.263 0.413 1.44 x10^-5
3 0.526 0.413 5.76 x10 ^ -5

a. Determine the rate law for the reaction
b. Calculate the value of the rate constant at 225 oC
c. Calculate the rate constant of formation of D when [A]=[B]= 0.75M

1. they vary with a higher number because boiling is way hotter than melting

14 days is the half-life of phosphorus-32

wher is the rest of the question

a. the law of proportion states the combination of 2 atoms in a specific ratio to produce multiple compounds such as the given statement of question ‘1st compound contains 88.8 % cu ’ indicates 88.8 g of cu is present along with 11.2 g oxygen in 100 g of compound whereas the statement ‘2st compound contains 79.9 % cu ’ indicates 79.9 g of cu is present along with 20.1 g oxygen in 100 g of compound

1st compound contains 88.8 g cu

for cu

m = 63 g /mol

atomic % = 88.8 /63 = 1.42

for o

m = 16 g /mol

atomic % = 11.2 /16 = 0.7

b. the emperical formula of 1st compound is

cu1.4o0.7
