MCQ (Single Correct Answer)

-1

For the reaction, 2A + B $$ \to $$ 3C + D, which of the following does not express the reaction rate?

$$ - {{d\left[ A \right]} \over {2dt}}$$

$$ - {{d\left[ C \right]} \over {3dt}}$$

$$ - {{d\left[ B \right]} \over {dt}}$$

$$ {{d\left[ D \right]} \over {dt}}$$

Consider the reaction : N_2(g) + 3H_2(g) $$ \to $$ 2NH_3(g)

The equality relationship between $${{d\left[ {N{H_3}} \right]} \over {dt}}$$ and $$ - {{d\left[ {{H_2}} \right]} \over {dt}}$$ is

$${{d\left[ {N{H_3}} \right]} \over {dt}} = - {{d\left[ {{H_2}} \right]} \over {dt}}$$

$${{d\left[ {N{H_3}} \right]} \over {dt}} = - {1 \over 3}{{d\left[ {{H_2}} \right]} \over {dt}}$$

$$ + {{d\left[ {N{H_3}} \right]} \over {dt}} = - {2 \over 3}{{d\left[ {{H_2}} \right]} \over {dt}}$$

$$ + {{d\left[ {N{H_3}} \right]} \over {dt}} = - {3 \over 2}{{d\left[ {{H_2}} \right]} \over {dt}}$$
