The emf of a standard cadmium cell is 1.02 V at 300 K. The temperature...
-4.0 x 10^-4 K^-1.
Explanation:
The temperature coefficient of a cell is defined as the rate of change of its emf with respect to temperature. Mathematically, it can be expressed as:
α = (1/E) * (dE/dT)
where α is the temperature coefficient, E is the emf of the cell, and dE/dT is the rate of change of emf with respect to temperature.
In this case, the emf of the cadmium cell is given as 1.02 V at 300 K. To find the temperature coefficient, we need to differentiate the emf with respect to temperature:
dE/dT = -4.0 x 10^-4 V/K
Substituting the given values in the formula for α, we get:
α = (1/1.02) * (-4.0 x 10^-4) = -3.92 x 10^-4 K^-1
Therefore, the temperature coefficient of the cadmium cell is -3.92 x 10^-4 K^-1.
