a reaction is in equilibrium as shown: a + b ⇌ c + d. calculate the equilibrium constant if the final…

Explanation:

Step1: Recall equilibrium - constant formula

For the reaction $A + B\rightleftharpoons C + D$, the equilibrium - constant expression is $K=\frac{[C][D]}{[A][B]}$.

Step2: Substitute the given concentrations

Substitute $[A]=9.60\ M$, $[B]=10.0\ M$, $[C]=4.00\ M$, and $[D]=4.00\ M$ into the formula: $K=\frac{4.00\times4.00}{9.60\times10.0}$

Step3: Calculate the value of $K$

$K=\frac{16.0}{96.0}= 0.167$

Answer:

0.167
