Catalyst is charged as high pressure pallets or tablets to
give high surface area to catalyst because rate of reaction
is directly proportional to surface area in any kind of
chemical or biological reaction

Answer / nilesh

May be I know that catalyst normally charged in powder form bcz at powder form increase the surface area of catalyst to compare the pellet form.

ELECTRICAL TECHNOLOGY - EXAMPLE 16.1 : According to Shockley equation, the I - V characteristic of a diode is approximated by I = IS [ exp (nVD / VT) - 1 ]. For silicon, let the reverse bias saturation current IS as 0.000000000001. If n is ideality factor with value of 1.5, VT as thermal voltage drop of 0.026 V at room temperature, what is the value of current I that passes through the silicon diode in the heater of evaporator when the forward voltage drop VD = 0.026 V? Please take note that exp is the exponential function with e(1) = 2.718, e(2) = 7.389.
