Question
Consider the reaction: A(g) + 2 B(g) --> 2 C(g) + D(g), Kc
A vessel is filled (initially) with equal concentrations of A and B, with no C or D present initially. Which one statement is definitely correct?
a) The concentrations of C and D will be equal at equilibrium
b) The concentrations of A and B will be equal at equilibrium
c) If Kc is very small (<<1), then either [C] or [D] (but not both) will be very small at equilibrium
d) If Kc is very large (>>1), then both [C] and [D] will be very large at equilibrium
e) If Kc is very large, then [B] will be very small at equilibrium
for each statement, give your reasoning as to why its correct or incorrect
Explanation / Answer
c) If Kc is very small (<<1), then either [C] or [D] (but not both) will be very small at equilibrium
