Answer #1

28) option c

Cr|Cr3+(1.0M)|| Ag+(1.0M)|Ag

27) option d

this is an endothermic reaction

26) option d

Q = [NO2]2 / [N2] [ O2]2=[2]2 / [0.10] [ 0.10]2 = 4 x 103

Q<Kc , reaction will proceed towards the product

25

Kc = [CH3CN] / CH3NC]

11 = [CH3CN] / 0.53

[CH3CN] = 11x 0.53 = 5.83 M
