Hello

how are you

i hope you are doing well

can you please help me with these questions

please do not forget the significant figures

thank you

3. Nitrogen and oxygen react to produce nitric oxide according to the following equation: N; (g) + 02 (5:) —~ 2 NO (g)The equilibrium constant for this reaction is 1.70 x 10'3. Suppose that 0.920 mol N2 and 0.700 mol 0: aremixed in a 3.00-L reaction vessel. What will be the concentrations of N2, 02, and NO when equilibrium isestablished? (Hint: assume that the amounts of N2 and O; that react are small—less than 10% of the startingamounts—and check your assumption when you have solved the equation.) 4. A mixture of gases is at equilibrium:2 NOCl (g) —» 2 N0 (3) + Cl2(g) AH = 78.38 H (a) Does the equilibrium shift to the lefi or to the right when some NO (g) is removed from thereaction mixture? (b) Does the equilibrium shift to the left or to the right when some NOCl (g) is removed from thereaction mixture? (c) [n which direction does the equilibrium shift as the temperature is lowered? (d) In which direction does the equilibrium shift as pressure is applied to the system?
