In Coulomb's law ` F = ( k_eq_1q_2)/(r^(2))` what are the factors on which the proportionality constant `k_e` depends?

Coulomb interaction between two point charges Q_1 and Q_2 if f = K frac(Q_1Q_2)(r^2) . The value of the constant of proportionality depends on the

Plot a graph showing the variation of Coulomb's force (F ) versus 1//r^(2) , where r is the distance between the two charges of each pair of charges ( 1 mu C , 2 mu C ) and ( 1 mu C , - 3mu C ) . Interpret the graphs obtained.

Force between two charges q_1 and q_2 separated by a distance r is proportional to q_1q_2//r^(2). Proportionality constant is

What is the the value of constant of proportionality in Coulomb's law for vaccum in CGS system?

What is the average K.E. of gas molecules depends on ?

Mention the factors that affect the rate of chemical reaction. For a reaction, the rate law is k[A]^(1//2)[B] . Can this reaction be an elementary reaction? The rate constant for the first-order decomposition of H_(2)O_(2) is given by the following equation log K =14.2 -(1.0 xx 10^(4)K)/(T) Calculate E_(a) for this reaction and rate constant k if its half life period be 200 min. (R=8.314 JK^(-1)"mol"^(-1))

The rate constant for the decomposition of N_(2) O_(5) at various temperatures is given below. Draw a graph between ln k and 1//T and calculate the values of A and E_a . Predict the rate constant at 30°C and 50°C.
