Question

In the reaction $X\left(g\right)+Y\left(g\right)\rightleftharpoons 2Z\left(g\right)$, $2$ mole of $X$, $1$ mole of $Y$ and $1$ mole of $Z$ are placed in a $10$ litre vessel and allowed to reach equilirbium. if final concentration of $Z$ is $0.2M$, then $K_c$ for the given reaction is:

• A. $1.60$
• B. $\frac{80}{3}$
• C. $\frac{16}{3}$
• D. none of these

Answer 1

The correct option is C $\frac{16}{3}$

Here the answer is wrong, and the correct answer is option(C)
