CH14-LECT3PROB Page 1 1. Why is the equilibrium in a reversible reaction described as dynamic ? 2. Consider the following reaction at a particular temp. NO 2 + N 2 O 3 NO Equilibrium conc. are: [ NO 2 ] = 1.25 M , [ N 2 O ] = 1.80 M and [ NO ] = 0.0015 What is the value of K c ? 3. For the following rxn, to what exponent must (RT) be raised in converting from K c to K p ? 2 SO 2 + O 2 2 SO 3 4. Equilibrium is established in the following rxn: A + B C + D K C = 10.0 At this point, which of the following must be true ? a) [ C ] [ D ] = [ A ] [ B ] b) [ C ] = [A] and [ D ] = [ B ] c) [ A ] [B ] = 0.10 x [ C ] [ D ] d) [ A ] = [ B ] = [ C ] = [ D ] = 10.0
