Equilibrium Question 810
Question: If the reaction between $ CO_2 $ and $ H_2O $ is $ CO_2+H_2O\rightarrow H_2CO_3\rightarrow {H^{+}}+HCO_3^{-} $ If $ CO_2 $ escapes from the system
Options:
A) pH will decrease
B) $ {H^{+}} $ concentration will decrease
C) $ H_2CO_3 $ concentration will be altered
D) The forward reaction is promoted
Show Answer
Answer:
Correct Answer: B
Solution:
$ CO_2+H_2O\rightarrow H_2CO_3\rightarrow {H^{+}}+HCO_3^{-} $ If $ CO_2 $ escapes, the equilibrium will shift to LHS and $ [ {H^{+}} ] $ concentration will decrease
