The correct Schrodinger's wave equation for a electron with total energy E and potential energy V is given by:

At a temperature of 0 K , the total energy of a gaseous diatomic molecule AB is approximately given by: E=E_(o)+E_(vib) where E_(o) is the electronic energy of the ground state, and E_(vib) is the vibrational energy. Allowed values of the vibrational energies are given by the expression: E_(vid)=(v-1/2)epsilon " " v=0, 1, 2, ....... " " epsilon=h/(2pi)sqrt(k/mu) " " mu(AB)=(m_(A)m_(B))/(m_(A)+m_(B)) where h is the planck's constant, is the vibration quantum number, k is the force constant, and is the reduced mass of the molecule. At 0K , it may be safely assumed that is zero, and E_(o) and k are independent of isotopic substitution in the molecule. Deuterium, D, is an isotope of hydrogen atom with mass number 2 . For the H_(2) molecule, k is 575.11 N m^(-1) , and the isotopic molar masses of H and D are 1.0078 and 2.0141 g mol^(-1) , respectively.

Assertion Total internal energy of oxygen gas at a given temperature is E of this energy 3/5 E is rotational kinetic energy. Reason Potantial energy of an ideal gas is zero.

If E is the total energy, U is the potential enegy and K is the kinetic energy of a mole of an ideal gas

A colliison between reactant molecules must occur with a certain minimum energy before it is effective in yielding Product molecules. This minimum energy is called activation energy E_(a) Large the value of activation energy, smaller the value of rate constant k . Larger is the value of activation energy, greater is the effect of temperature rise on rate constant k . E_(f) = Activation energy of forward reaction E_(b) = Activation energy of backward reaction Delta H = E_(f) - E_(b) E_(f) = threshold energy The rate constant of a certain reaction is given by k = Ae^(-E_(a)//RT) (where A = Arrhenius constant). Which factor should be lowered so that the rate of reaction may increase?

Arrhenius equation k=Ae^(-E_(a)//RT) If the activation energy of the reaction is found to be equal to RT, then [given : (1)/(e )=0.3679 ]
