Question

A 0.100 M sample of SO2 reacts with 0.060 M O2 to produce SO3 by the reaction shown below. There was no SO3 present initially. The concentration of O2 measured at equilibrium is found to be 0.020 M. What are the equilibrium concentrations of SO2 and SO3? 2 SO2(g) + O2(g) ==> 2 SO3(g) selections: none of these [SO2] = 0.040M, [SO3] = 0.060M [SO2] = 0.020M, [SO3] = 0.080M [SO2] = 0.080M, [SO3] = 0.120M [SO2] = 0.080M, [SO3] = 0.080M

          A 0.100 M sample of
SO2 reacts with
0.060 M O2 to produce
SO3 by the reaction shown below.  There was no
SO3 present initially.  The concentration of
O2 measured at equilibrium is found to be
0.020 M.  What are the equilibrium
concentrations of SO2 and SO3? 
                 
                 
                 
                 
                 
  
2 SO2(g) + O2(g) 
==>  2 SO3(g)
selections:
none of these
 
[SO2] = 0.040M,  [SO3] = 0.060M
 
[SO2] = 0.020M,  [SO3] = 0.080M
 
[SO2] = 0.080M,  [SO3] = 0.120M
 
[SO2] = 0.080M,  [SO3] = 0.080M
