(a) Nitrogen gas is made from sodium azide by the following reaction. If 3 mols of sodium azide is used for this reaction, how many litres of nitrogen can be produced at 298K and 1.05 atm? (Assume that nitrogen is a perfect gas at the given conditions). 2 NaNg(s) 2 Na(s) + 3 N2 (g) (b) Calculate the root mean square speed of nitric oxide gas at 30 °C? (c) A sample of 2 mol of monatomic perfect gas at 3 atm pressure expands three times its initial volume when the pressure is lowered. Calculate the final pressure. Also calculate the initial volume if the temperature is maintained constant at 300K during this process. (d) When Charle's law is verified by plotting a graph for the following data, a student obtained the equation y=100x-273 for the plot obtained. Teacher wants the student to redo the graph so that the equation will not have a y-intercept. How should the graph be modified? What will be the new equation and slope?

Expert Solution
Step 1

Since you have posted multiple unrelated questions, we are entitled to answer the first only.

 

Step 2

a) The balanced reaction taking place is given as,

=> 2 NaN3 (s) -------> 2 Na (s) + 3 N2 (g)

Given: Moles of NaN3 reacting = 3 mol.

Temperature = 298 K

And pressure of gas = 1.05 atm.

From the above balanced reaction we can see that 2 moles of NaN3 is reacting to produce 3 moles of nitrogen gas.

Hence moles of nitrogen gas produced = Moles of NaN3 reacting X 32 = 3 X 3 2 = 4.5 mol.
