Consider the following reaction:

$C_2{H}_4(g)+H_2(g)C_2{H}_6(g)$

In the boxes below write your answers to the following:

The equilibrium constant numerator $($use the form $[NH{4}^{{?}^{{?}^{?}}}1+{]}^{{?}^{{?}^{?}}}2[SO{4}^{{?}^{{?}^{?}}}2-]$; make sure you use square brackets$)$

The equilibrium constant denominator $($same form as $1.)$

If there is no reactant or product that can go into the equilibrium constant, write the number $1.$

$1.$

$2.$
