Answer :
Final answer:
The concentration of B(g) when the system reaches equilibrium is 0.50M.
Explanation:
To find the concentration of B(g) at equilibrium, we can use the equilibrium constant expression:
Kc = [B(g)] / [A(g)]
Given that the initial concentration of A(g) is 1.0M and that of B(g) is 0.0M, we can substitute these values into the equation:
0.50 = [B(g)] / 1.0
Cross-multiplying, we get:
[B(g)] = 0.50 * 1.0
[B(g)] = 0.50M
Therefore, the concentration of B(g) when the system reaches equilibrium is 0.50M.
