Solution Summary: The author explains how the oxidation number of As, S and N in the reaction with Nitric acid should be determined.
The presence of arsenic in a sample that may also contain another Group 5A element, antimony, can be confirmed by first precipitating the As3+ and Sb3+ ions as yellow solid As2S3 and orange solid Sb2S3. If aqueous HCI is then added, only Sb2S3 dissolves, leaving behind solid As2S3. The As2S3 can then be dissolved using aqueous HNO3.
Finally, the presence of arsenic is confirmed by adding AgNO3 to the solution of H3AsO4 to precipitate a reddish brown solid AgxAsOy The composition of this solid is As, 16.199% and Ag, 69.964%.
(a) What are the oxidation numbers of As, S, and N in the reaction of As2S3 with nitric acid?
(b) What is the formula of the reddish brown solid AgxAsOy?
The number of microstates corresponding to each macrostate is given by N. The dominant macrostate or configuration of a system is the macrostate with the greatest weight W. Are both statements correct?
For the single step reaction: A + B → 2C + 25 kJ
If the activation energy for this reaction is 35.8 kJ, sketch an energy vs. reaction coordinate diagram for this reaction. Be sure to label the following on your diagram: each of the axes, reactant compounds and product compounds, enthalpy of reaction, activation energy of the forward reaction with the correct value, activation energy of the backwards reaction with the correct value and the transition state.
In the same sketch you drew, after the addition of a homogeneous catalyst, show how it would change the graph. Label any new line "catalyst" and label any new activation energy.
