Equilibrium Question 705
Question: When heated, ammonium carbamate decomposes as follows: $ NH_4COONH_2(s)\rightarrow 2NH_3(g)+CO_2(g) $ . At a certain temperature, the equilibrium pressure of the system is 0.318 atm. $ K_{p} $ for the reaction is:
Options:
A) 0.128
B) 0.426
C) $ 4.76\times {10^{-3}} $
D) None of these
Show Answer
Answer:
Correct Answer: C
Solution:
$ P_{total}=3P $
$ \Rightarrow P=\frac{0.318}{3}=0.106 $
$ \therefore K_{p}=4P^{3}=4.76\times {10^{-3}} $
