Question

For the reaction $A\left(g\right)+2B\left(g\right)\rightleftharpoons 2\left(g\right)+D\left(s\right)$, 2 moles of A, 3 moles of B and 1 mole of C are present in 10L vessel if $K_C$ for the reaction is 3.6, the reaction will proceed in:-

• A. Forward direction
• B. Backward direction
• C. Neither direction
• D. None of these

Answer 1

The correct option is A Forward direction

$A\left(g\right)+2\left(B\right)\left(g\right)\rightleftharpoons 2C\left(g\right)+D\left(s\right)Q_C=\frac{[C{]}^2}{\left[A\right][B{]}^2}=\frac{{\left(\frac{1}{10}\right)}^2}{\frac{2}{10}.{\left(\frac{3}{10}\right)}^2}=\frac{10}{18}{Q}_C<K_C$
Reaction will move in forward direction
