Kp and Kc Relationship and Characteristics of K
question_answer
For the reaction \[{{H}_{2}}(g)+{{I}_{2}}(g)\]⇌ \[2HI(g)\] at \[721K\] the value of equilibrium constant \[({{K}_{c}})\] is 50. When the equilibrium concentration of both is \[0.5\,M\], the value of \[{{K}_{p}}\] under the same conditions will be [CBSE PMT 1990]
A) 0.002
B) 0.2
C) 50.0
D) \[50/RT\]
Correct Answer:
C
Solution :
For the reaction \[{{H}_{2}}+{{I}_{2}}\] ⇌ 2HI \[\Delta n=0\] So \[{{K}_{p}}={{K}_{c}}\] \50.0
