For an elementary bimolecular gas phase reaction, activation energy is 5.5 kJ $mo{l}^{-1}$. Enthalpy of activation, in kJ $mo{l}^{-1}$, at 300 K is ________ ($R=8.314J{K}^{-1}mo{l}^{-1}$)

The titration of a strong acid with a strong base is represented by the plot

Of the following inequalities, the criterion/criteria for spontaneity of a chemical reaction is/are

(i) $(\Delta G{)}_{T,P}<0$ (ii) $(\Delta U{)}_{S,V}>0$ (iii) $(\Delta S{)}_{U,V}>0$

A protein sample consists of an equimolar mixture of ribonuclease (molar mass = 13.7 kg $mo{l}^{-1}$), hemoglobin (molar mass = 15.5 kg $mo{l}^{-1}$), and myoglobin (molar mass = 17.2 kg $mo{l}^{-1}$). The statement that is true about the weight-average molar mass ($\overline{M_w}$), the number-average molar mass ($\overline{M_n}$), and the polydispersity index (PDI) for this sample is

The band structure given below represents a
