Answer to Question #208151 in Physical Chemistry for Aditya Venkatesh A

Question

Nitrogen and oxygen react to produce nitric oxide according to the following equation: N2 (g) + O2 (g) → 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 O2 are mixed in a 3.00-L reaction vessel. What will be the concentrations of N2, O2, and NO when equilibrium is established? (Hint: assume that the amounts of N2 and O2 that react are small—less than 10% of the starting amounts—and check your assumption when you have solved the equation.)

Answer 1

When the reaction begins, we have zero amount of NO, this means we are dealing witha the case where reaction quotient is less than equilibrium constant
