Question

write the value of 2.303 rtin nerst equation
​

Answer 1

The value of 2.303*RT/zF is 58 mV at room temperature.

• As we know that the Nernst equation is related to the movement of a single ion lineage through selective channels, on is supposed to be related only to the concentration of that ion. So when handling K ion, one need not be concerned about Na ion.

How The value of 2.303*RT/zF is 58 mV at room temperature?

• R = 8.135; T = 273 + 25 (room temperature of 25 oC); z = 1; F = 9.684 × 104.

$2.303 \times \frac{8.135 \times 298}{1 \times 96840} \\ = 0.0578$

• Approve for presently that this has the units of Volts. Since this is a lesser value it is most conveniently conveyed in mV (1/1000 of a volt), in which case it comes to be 57.8 mV. For most bases like for calculations, this is rounded up to 58 mV.
