In an estimation of bromine by Carius method, 1.6 g of an organic compound gave 1.88 g of AgBr. The mass percentage of bromine in the compound is _______.
(Atomic mass, Ag = 108, Br = 80 g mol^–1)

The set that contains atomic numbers of only transition elements, is :

Consider the following reactions
'A' is :

The variation of equilibrium constant with temperature is given below :

Temperature	Equilibrium Constant
T1 = 25oC	K1 = 10
T2 = 100oC	K2 = 100

The values of $$\Delta $$H^o, $$\Delta $$G^o at
T₁ and $$\Delta $$G^o at T₂ (in kJ mol^–1) respectively, are close to :
[Use R = 8.314 J K^–1 mol^–1]
