When the first electron gain enthalpy $$\left( {{\Delta _{eg}}H} \right)$$ of oxygen is $$-$$ 141 kJ/mol, its second electron gain enthalpy is :

For the reaction, 2A + B $$ \to $$ products, when the concentrations of A and B both were doubled, the rate of the reaction increased from 0.3 mol L^$$-$$1s^$$-$$1 to 2.4 mol L^$$-$$1s^$$-$$1. When the concentration of A alone is doubled, the rate increased from 0.3 mol L^$$-$$1s^$$-$$1 to 0.6 mol L^$$-$$1s^$$-$$1.

The major product obtained in the following reaction is :
