In the complex [M (en)_{2} (Ox)]
Cl For the central metal ion M^{3+}

The primary valance is = +3

The secondary valance = 6

sum of primary valance and secondary valance = 3+6 = 9

In this case

k = x min^{−1} and [A_{0}]
= 0.01M = 1 × 10^{−2}M

t = 1 hour = 60 min

[A]= 1 × 10^{−2} ( e^{−60x})

The refractive index (n) of the glass is different for different colours. For violet n is high. ∴ Violet travel with low speed, so deviation is high.

Hint: Since V=0 along equatorial line

de
Broglie wavelength for an electron

λ_{e}=
*h* / √(2mE) ;

λ_{e} ∝_{ }1/√E ;

λ_{e}^{2}^{ }∝_{ }1/E ------------- (1)

For
photon

λ_{p}=
*hc* / E ;

λ_{p} ∝_{ }1/E ------------- (2)

From
equation (1) and (2), we have So,

λ_{p} ∝ λ_{e}^{2}
