Some Basic Concepts Of Chemistry Question 148
Question: If 3 moles of $ H _2 $ and 1 mole of $ N _2 $ are completely converted into $ NH _3, $ the ratio of initial and final volume at the same temp. and pressure will be:
Options:
A) 1
B) 3
C) 2
D) 4.20
Show Answer
Answer:
Correct Answer: C
Solution:
[c] $ N _2 $ $ + $ $ 3H _2 $ $ \xrightarrow{{}} $ $ 2NH _3 $ Initially 1 3 0 Final 0 0 2 Pressure $ \alpha $ no. of moles $ H _{i} $ = $ 1+3=4 $
$ H _{f} $ = 2 $ P _{i}\text{/}P _{f} $ = $ 4\text{/}2=2 $
