CBSE · Class 11 · Chemistry · Chemical ThermodynamicsFor the reaction $N2(g) + 3H2(g) \rightarrow 2NH3(g)$, what is the value of $\Delta ng$?
Step-by-Step Solution
$\Delta n_g = n_p(g) - n_r(g)$. Moles of gaseous products = 2. Moles of gaseous reactants = 1 + 3 = 4. Therefore, $\Delta n_g = 2 - 4 = -2$.
