Question

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

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

Initially, the scientist fills an evacuated 4.956 L flask with 9.570 x 10-1 moles of species A. Upon equilibrium, it is determined that the concentration of A is 1.724 x 10-1 M. Calculate Kc.
