A) \[{{K}_{p}}={{K}_{c}}\]
B) \[{{K}_{c}}=2{{K}_{p}}\]
C) \[{{K}_{p}}>{{K}_{c}}\]
D) \[{{K}_{c}}={{K}_{p}}{{(RT)}^{2}}\]
Correct Answer: A
Solution :
\[2HI(g)\rightleftharpoons {{H}_{2}}(g)+{{I}_{2}}(g)\] \[\Delta n\] = (no of gaseous product) - (no of gaseous reactant) \[\Delta n=(2-2)=0\] \[{{K}_{p}}={{K}_{c}}{{(RT)}^{\Delta n}}\] \[{{K}_{p}}={{K}_{c}}{{(RT)}^{0}}\] When. \[\Delta n=0,\] then \[{{K}_{p}}={{K}_{c}}\] So, \[{{K}_{p}}={{K}_{c}}\]
