Answer:
The equilibrium concentration of NO in the gas mixture should be 0.578 M
Explanation:
We have equilibrium data for the chemical reaction in the gas phase:
SO2(g)+NO2(g)⇌NO(g) +SO3(g)
The equilibrium constant (Keq) for this reaction is 10.8.
Data for the components involved in this equilibrium are:
[SO3] = 1.7 M
[NO] = Unknown
[NO2] = 1.3 M
[SO2] = 0.07 M
We can express the Equilibrium constant as the multiplication of the concentrations of products divided by the multiplication of the concentration of reagents. After that, we can isolate [NO] concentration and find its value.
Replacing the values given in the problem
Finally, the equlibrium concentration is [NO] = 0.578 M
Answer:
Explanation:
Chemically, we can have a reaction between chlorine gas and solid sodium
This reaction is actually explosive and would produce fine powder of sodium chloride
We have the reaction as follows:
Essentally, what we can deduce from here is that we do not need to add water to the flask. Except for the reason that we would want the sodium chloride solid in the solution form, there is absolutely no reason to add water to the flask as the reaction would proceed normally
