The differential rate law for the reaction H2 + I2 $$\to$$ 2HI is
A
$$- {{d\left[ {{H_2}} \right]} \over {dt}}$$ = $$- {{d\left[ {{I_2}} \right]} \over {dt}}$$ = $$- {{d\left[ {{HI}} \right]} \over {dt}}$$
B
$${{d\left[ {{H_2}} \right]} \over {dt}}$$ = $${{d\left[ {{I_2}} \right]} \over {dt}}$$ = $${{d\left[ {{HI}} \right]} \over {dt}}$$
C
$${1 \over 2}{{d\left[ {{H_2}} \right]} \over {dt}}$$ = $${1 \over 2}{{d\left[ {{I_2}} \right]} \over {dt}}$$ = $$- {{d\left[ {{HI}} \right]} \over {dt}}$$
D
$$- 2{{d\left[ {{H_2}} \right]} \over {dt}}$$ = $$- 2{{d\left[ {{I_2}} \right]} \over {dt}}$$ = $${{d\left[ {{HI}} \right]} \over {dt}}$$
