Question

What is the equilibrium constant equation for the chemical process below?
2A + B2 —> A₂B2

Answer 1

Let's see

$\\ \rm\dashrightarrow k=\dfrac{Concentration\:of\: products}{Concentration\:of\: reactants}$

$\\ \rm\dashrightarrow k=\dfrac{\left[A_2B_2\right]}{\left[A\right]^2\left[B\right]}$
