Keq for this reaction is 3.63.
a + 2b  c

the data in the table shows the concentrations of the reactants and product in two different
reaction mixtures at the same temperature. does the data provide evidence that both reactions
are at equilibrium?
concentrations of a, b and c
a (mol/l) b (mol/l) c (mol/l)
0.500 0.621 0.700
0.250 0.525 0.250

a.) no, the data give different keq values
b.) no, the concentration of c is lower than b in the second mixture
c.) yes the keq remains constant
d.) yes, there is always produ
