Consider the following equilibrium reaction:2NO(g) + Br2(g) ⇌ 2NOBr(g)If the initial concentration of NO is 0.10 M, Br2 is 0.20 M, and NOBr is 0.40 M, what would be the concentration of NOBr when additional Br2 is added such that its concentration is doubled? Calculate the new equilibrium concentration of NOBr assuming all other conditions remain the same.

Consider the following equilibrium reaction at a constant temperature: 2NO(g) + O2(g) ⇌ 2NO2(g)Initially, the reaction mixture contains 0.50 mol NO, 0.40 mol O2, and 0.10 mol NO2 in a 1.0 L container. The system is disturbed by contracting the volume to 0.50 L. Calculate the effect of changing the volume on the equilibrium position and calculate the concentration of each species at equilibrium.
