How surface tension depends on temperature?

The activation energy of a reaction is zero. Will the rate constant of the reaction depend upon temperature? Give reason.

Assertion :Threshold energy of a reaction is dependent of temperature. Reason :The energy of activation decreases with increase in temperature.

In each of the following question, an Assertion (A) is following by a corresponding Reason (R ). Use the following keys to choose the appropriate answer. Assertion : Molarity of a solution does not depend upon temperature whereas molality depends. Reason : Molarity and molality both depend only on the number of moles of solute particles.

Surface tension changes with temperature. What is the value of angle of contact for pure water?

Maxwell and Boltzmann have shown that actual distribution of molecular speeds depends on temperature and molecular mass. At the same temperature which will move faster, N_2 or Cl_2 ?
