Question

Which one
?

For the generic reaction, A(g) = B(g), consider each value of K and the initial concentration of reactant A. For which set of values does the x is small approximation most likely to apply? o K = 1.0; [A] = 5.0 x 10-3 M. O K = 1.0 x 10-5; [A] = 0.00250 M. O K = 1.0 X 10-3; [A] = 0.00250 M O K = 1.1 x 10-4; [A] = 1.4 M
