The mole fraction of a solute in a solution is 0.1. At 298 K, molarity of this solution is the same as its
molality. Density of this solution at 298 K is 2.0 g cm–3 . The ratio of the molecular weights of the solute and solvent, $$\left( {{{M{W_{solute}}} \over {M{W_{solvent}}}}} \right)$$, is

According to the Arrhenius equation,
A
a high activation energy usually implies a fast reaction
B
rate constant increases with increase in temperature. This is due to a greater number of collisions whose energy exceeds the activation energy
C
higher the magnitude of activation energy, stronger is the temperature dependence of the rate constant.
D
the pre-exponential factor is a measure of the rate at which collisions occur, irrespective of their
energy.
