Show that their for two half reactions having potentials `E_1` and `E_2` which are combined to give a third half reactions having potential `E_3` is
`E_3=(n_1E_1+n_2E_2)/n_3`

Show that 2.6 < e < 3.

when two half-cells of electrode potential of E_1 and E_2 are combined to form a half cell of electrode potential E_3 , then (when n_1,n_2"and"n_3 are no. of electrons exchanged in first second and combined half-cells:

True or false Two events E_1 and E_2 are said to be mutaully exclusive iff E_1capE_2=phi

If E_1 and E_2 are two independent events associated with an experiment, then show that P(E_1cupE_2)=1-P(E_1^c)P(E_2^c)

If E_1 and E_2 are independent events associated with an experiment such that P(E_1)=P_1 and P(E_2)=P_2 . Find P(E_1 and E_2) .

Fill in the Blanks : If E_1 and E_2 are independent events, then P( E_1 nn E_2 ) =..

Fill ups If E_1 and E_2 are independent events associated with an expeirment then P(E_2^c//E_1^c) =1-…………….. .

The activation energies of two reactions are E_1 and E_2 (E_1 > E_2) . If the temperature of the system is increased from T_1 to T_2 the rate constant of the reaction changes from k_1 to k_1' in the first reaction and k_2 to k_2' in second reaction, predict which of the following expression is correct ?

Fill ups Two events E_1 and E_2 associated with an experiment are independent iff P(E_1capE_2) =………………….

From the fllowing half-cell reactions and their standard potentials ,what is the smallest possible standard e.m.f for spontaneous reactions? PO_4^(3-)(aq)+2H_2O(l)+2e^(-)toHPO_3^(2-)+3OH^(-)(aq), E^(@)=-1.05V PbO_2(s)+H_2O(l)+2e^(-)toPbO(s)+2OH^(-)(aq),E^(@)=+0.28 V
