Consider the following reaction ${\mathrm{N}}_{2\left(\mathrm{g}\right)}+3{\mathrm{H}}_{2\left(\mathrm{g}\right)}\to 2{\mathrm{NH}}_{3\left(\mathrm{g}\right)}$. The rate of the reaction in terms of N₂ at T (k) is. What is the value of$\frac{\mathrm{d}\left[{\mathrm{H}}_2\right]}{\mathrm{dt}}\left(\text{ in mole. }{\mathrm{lit}}^{-1}\cdot {\sec }^{-1}\right)$ at the same temperature?
