The reaction a→ b is to be carried out isothermally in a continuous-flow reactor, to consume 99% of a (ca = 0.01 cao). the entering molar flow rate is 5 mol/min, and the entering volumetric flow rate is 10 l/min. the reaction rate -ra is first order in a, and the reaction rate constant is 0.36 min-1.

answersilicon (si); oxygen (o);

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
