Ractivation = Kc*(1-αemission)
This formula uses 3 Variables
Variables Used
Rate of Activation - (Measured in Mole per Cubic Meter) - Rate of Activation is the rate at which minimum amount of extra energy required by a reacting molecule to get converted into product.
Equilibrium Constant - (Measured in Mole per Cubic Meter) - Equilibrium Constant is the value of its reaction quotient at chemical equilibrium.
Degree of Dissociation of Emission - Degree of Dissociation of Emission is defined as the fraction of solute ions( carrying current) dissociate at specific given temperature.
STEP 1: Convert Input(s) to Base Unit
Equilibrium Constant: 60 Mole per Liter --> 60000 Mole per Cubic Meter (Check conversion ​here)
Degree of Dissociation of Emission: 0.5 --> No Conversion Required
STEP 2: Evaluate Formula
