H_(3)A is a weak triprotic acid (K_(a1)=10^(-5),K_(a2)=10^(-9),K_(a3)=10^(-13) What is the value of pH of 0.1 M H_(3)A (aq.) solution ? Where pX=-log X and X= [[A^(3-)]]/[[HA^(2-)]]
At 527^(@)C , the reaction given below has K_(c)=4 NH_(3)(g)hArr(1)/(2)N_(2)(g)+(3)/(2)H_(2)(g) what is the K_(p) for the reaction ? N_(2)(g)+3H_(2)(g)hArr2NH_(3)(g)
Van's Hoff's equation shows the effect of temperature on equilibrium constants K_(c) and K_(p) .the K_(P) varies with tempertaure according to the realation:
The following mechanism has been proposed for the exothermic catalyzed cmplex reaction: A + B overset("Fast")rarr IABoverset(k_(1))rarrAB+Ioverset(k_(2))rarrP+A If k_(1) is much smaller than k_(2) , the most suitable qualitative plot of potential energy (PE) versus reaction coordinates for the above reaction is a) b) c) d)
For a gaseous reaction aA(g)+bB(g)hArrcC(g)+dD(g) equilibrium constants K_(c),K_(p) and K_(x) are represented by the following reation K_(c)=([C]^(c)[D]^(d))/([A]^(a)[B]^(b)),K_(p)=(Pc^(c).P_(D)^(d))/P_(A)^(a) and Kx=(x_(C)^(c).x_(D)^(d))/(x_(A)^(a).x_(B)^(b) where [A] represents molar concentrationof A,p_(A) represents partial pressure of A and P represents total pressure, x_(A) represents mole fraction of A For the reaction SO_(2)Cl_(2)(g)hArrSO_(2)(g)+Cl_(2)(g),K_(p)gtK_(x) is obtained at :
