Question

A researcher is studying the decomposition of A as shown by the general reaction below:

1 A(g) 2 B(g) + 4 C(g)

Initially, the scientist fills an evacuated 5.868 L flask with 4.510 x 10-1 moles of species A. Upon equilibrium, it is determined that the concentration of A is 6.448 x 10-2 M. Calculate Kc.
