Current Question (ID: 8407)

Question:

\text{The value of the equilibrium constant for a particular reaction is } 1.6 \times 10^{12}. \text{ When the system is in equilibrium, it will include:}

Options:

1. $\text{All reactants}$
2. $\text{Mostly reactants}$
3. $\text{Mostly products}$
4. $\text{Similar amounts of reactants and products}$

Solution:

\text{Hint: The value of equilibrium constant is very large. Then reaction almost completed} \text{Step 1:} \text{If } K_c > 10^3\text{, products predominate over reactants, i.e., if } K_c \text{ is very large, the reaction proceeds nearly to completion. The concentration of the product is very high as compared to the reactant.} \text{Step 2:} A \rightleftharpoons B K_c = \frac{[B]}{[A]} = 1.6 \times 10^{12} \text{The equilibrium constant value is very high, thus, the concentration of the product is more as compared to the reactant.}
