Question

for the reaction, N2 + 3 H2 gives 2 NH3, if d[NH3]/dt is equal to 2 *10 ^- 4 mol /L/ sec
the value of -d[H2]/dt would be....​

Answer 1

Answer:

According to the Theoretical Chemical Kinetic equation for a chemical reaction

We can say,

-1/1 d(N2)/dt = -1/3 d(H2)/dt = 1/2 d(NH3)/dt

so,

-d(H2)/dt = 3/2 * d(NH3)/dt = 3/2* 2*10^-4 mol/L

And hence,

-d(H2)/dt = 3*10^-4 mol / L
