If `K_(a_1),K_(a_2)` and `K_a_3)` be the first, second and third dissociation constant of `H_(3)PO_(4)` and `K_(a_1)gtgt K_(2_a) gtgtK_(a_3)` whis is/are correct :
What is the ratio of the rate constants K_(1) and K_(2) ?
A chemical reaction occurs in three paths having rate constants k_(1),k_(2) and k_(3) respectively. If Ea_(1),Ea_(2) and E_(a_(3) are 4,5 and 8kJ respectivel and overall rate constant k=(k_(1)k_(3))/(k_(2)) . Assuming A_(av)=(A_(1)A_(3))/(A_(2)) the overall energy of activation in kJ is __________
If a_1,a_2,a_3,a_4 are the coefficients of 2nd, 3rd, 4th and 5th terms of (1+x)^n respectively then (a_1)/(a_1+a_2) , (a_2)/(a_2+a_3),(a_3)/(a_3+a_4) are in
If a_1,a_2, a_3,a_4 are the coefficients of 2nd, 3rd, 4th and 5th terms of respectively in (1+x)^n then (a_1)/(a_1+a_2)+(a_3)/(a_3+a_4)=
A certain endothermic reaction: Ato Product, DeltaH=+ve proceeds ina sequence of three elementary steps with the rate constant K_(1),K_(2) and K_(3) and each one having energy of activation E_(1),E_(2) and E_(3) respectively at 25^(@)C . The observed rate constannt for the reaction is equal to K_(3)sqrt((K_(1))/(K_(2))) . A_(1),A_(2) and A_(3) are Arrhenius parameters respectively. Which represents the correct value if catalyst is not present:
