Question

plz solve it for me​

Answer 1

Answer:

-51 g/hr

Explanation:

You need to use a fundamental formula in chemical kinetics:

$For \ aA+bB \to cC$

$\frac{-1}{a}\frac{d[A]}{dt}=\frac{-1}{b}\frac{d[B]}{dt}=\frac{1}{c}\frac{d[C]}{dt}$

NOTE: This formula works for any no. of reactants and product....just add new terms in equation analogously.

Here,

$\frac{-1}{3}\frac{d[H_2]}{dt}=\frac{1}{2}\frac{d[NH_3]}{dt}\\\frac{d[H_2]}{dt}= \frac{-3}{2}\times 34\\=-51$

The minus sign is here to denote decrease in the quantity of H2.
