k_p=(n_C^c * nD^d/nA^a * nB^b)*(p/n)^{delta n_g}

WHEN INERT GAS IS ADDED AT CONST. PRESSURE

case1  delta n_g = 0 therefore (p/n)^{delta n}g=1

k_p=const. equ. remains unchanged

case 2 delta n_g > 0 total n increases , (p/n)^{delta n}g decreases hence to keep k_p const. value of (n_C^c * nD^d/nA^a * nB^b) increases

therefore rex. proceed in forward direction

case 3 delta n_g<0 total n increases (p/n)^{delta n}g increases hence to keep k_p const. value of (n_C^c * nD^d/nA^a * nB^b)

decreases therefore rex. proceed in backward direction

Inclined mirrors : number of images







(a) When 360⁰ is exactly divisible by θ⁰ and 360⁰/θ⁰ is an even integer then the number of images formed is















    n = 360/θ −1 (whatever may be location of the object)















(b) When 360⁰ is not exactly divisible by θ, then the number of images formed is

     = integer value of n (where n = 360/θ)

Unit vector



Unit vector has a magnitude of one and is directed in a particular direction. It does not have dimension or unit like most other physical quantities. Thus, multiplying a scalar by unit vector converts the scalar quantity into a vector without changing its magnitude, but assigning it a direction.

Conventionally, unit vectors along the rectangular axes is represented with bold type face symbols like :  i , j and k



                      

 

Thermo e.m.f. : e = αθ +βθ²/2        (where θ = θ_H = θ_C)

 

Neutral temperature: θ_N = -(α/β)      [(de/dθ)_θn=0]

Temperature of inversion: θ_Ν=(θ₁ + θ_C)/2  [θ₁-θ_n=θ_n-θ_c]

 

Thermoelectric power or Seebeck Coefficient:  S =de/dθ = α + βθ

Chemical effect of current:

(a) Faradays first law of electrolysis: m = Zq = ZIt

(b) Faradays second law of electrolysis:

(i) m ∝ W (W = ECE) or m/W  =  constant  (where W = atomic weight/valency)

(II) as m₁/m₂=z₁/z₂  and  m₁/m₂=w₁/w₂;  so  z₁/z₂=w₁/w₂

(c) Faraday : 1 Faraday = 96,500 Coulomb

(d) w/z= F =Faraday's constant
