When heated ammonium carbamate decomposes as follows

{NH}_4 {COONH}_2\text{(s)} \Leftrightarrow 2 {NH}_3(\mathrm{g})+{CO}_2(\mathrm{g})

At a certain temperature, the equilibrium pressure of the system is

0.318 \mathrm{~atm}, {K}_{{p}}

for the reaction is

View answer and explanation

Correct option: C

4.76 \times 10^{-3}

Option C (

4.76 \times 10^{-3}

) is correct because it is calculated using the equilibrium pressure and the stoichiometry of the reaction to find Kp.
