Expert Solution
Step 1
The reaction given is
A (aq) + 2 B (s) --------> C (s) + 2 D (aq)
Step 2
Assuming y concentration of A reacts to reach equilibrium
Hence concentration of D formed at equilibrium = [D] = 2y
And concentration of A remaining at equilibrium = [A] = initial - reacted = 0.48 - y
Since the equilibrium constant Kc <<<< 1
Hence negligible concentration of A will react.
Hence [A] = 0.48 - y = 0.48 M approx
