Question
Which of the followings is incorrect?
Answer: Option D
:
D
a) According to law of mass action,rate of a chemical reaction is proportional to molar concentration of reactants.
b) At equilibrium,
b) Though value of equilibrium constant doest not charge, catalysts increase the rate of both the forward and backward reactions.
c) lnk2k1=△HR(1T1−1T2)
IfT2>T1,
Hence this Optionis incorrect

a) According to law of mass action,rate of a chemical reaction is proportional to molar concentration of reactants.
b) At equilibrium,
- Products are present predominantly if Kc>1
- Products are present predominantly if Kc<1
b) Though value of equilibrium constant doest not charge, catalysts increase the rate of both the forward and backward reactions.
c) lnk2k1=△HR(1T1−1T2)
IfT2>T1,
- K2<K1if△H>0 i.e. reaction is endothermic
- K2<K1if△H>0 i.e. reaction is exothermic
Hence this Optionis incorrect
