Given the reaction between 2 gases represented by A2 and B2 to give the compound AB(g).
A2(g) + B2(g) 2 AB(g).
At equilibrium, the concentration
of A2 = 3.0 x 10-3 M
of B2 = 4.2 x 10-3 M
of AB = 2.8 x 10-3 M
If the reaction takes place in a sealed vessel at 527oC, then the value of Kc will be:
1.9
0.62
