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
$$ - 2{{d\left[ {{H_2}} \right]} \over {dt}}$$ = $$ - 2{{d\left[ {{I_2}} \right]} \over {dt}}$$ = $${{d\left[ {{HI}} \right]} \over {dt}}$$
