Question

The differential rate expression for the reaction ${{m{H}}_2} + {{m{I}}_2} 	o 2{m{HI}}$ is:

Accepted Answer

$ - 2\frac{{d\left[ {{{\rm{H}}_2}} \right]}}{{dt}} = - 2\frac{{d\left[ {{{\rm{I}}_2}} \right]}}{{dt}} = \frac{{d\left[ {{\rm{HI}}} \right]}}{{dt}}$

Answer

$\frac{{ - d\left[ {{{\rm{H}}_2}} \right]}}{{dt}} = \frac{{ - d\left[ {{{\rm{I}}_2}} \right]}}{{dt}} = \frac{{ - d\left[ {{\rm{HI}}} \right]}}{{dt}}$

Answer

$\frac{{d\left[ {{{\rm{H}}_2}} \right]}}{{dt}} = \frac{{d\left[ {{{\rm{I}}_2}} \right]}}{{dt}} = \frac{{d\left[ {{\rm{HI}}} \right]}}{{dt}}$

Answer

$\frac{1}{2}\frac{{d\left[ {{{\rm{H}}_2}} \right]}}{{dt}} = \frac{1}{2}\frac{{d\left[ {{{\rm{I}}_2}} \right]}}{{dt}} = \frac{{d\left[ {{\rm{HI}}} \right]}}{{dt}}$
