Yes. Why? The Nernst equation to calculate the Ecell for non standard conditions is as follows:

Ecell = E°cell - (RT/nF ) lnQ

so T can be any temperature in Kelvin

The other version of the Nernst equation is for standard conditions:

Ecell = E°cell - (0.0592/n) logQ

This applies only at room temperature. When at 25°C, (RT/F )becomes a constant of 0.0592. So if you are determining the Ecell at room temp use the second equation, for any other condition use the first equation.

Cheers!

How to calculate hydrogen electrode?

The standard hydrogen electrode potential (SHE) is defined as 0 V by convention. It serves as a reference point to measure the electrode potential of other half-reactions. It is not calculated but rather chosen as a reference point for comparison in electrochemical reactions.


The final sanitizing rinse temperature must be lower in a chemical sanitizing dishwasher than in other types of dishwashers because lower temperatures?

Chemical sanitizing dishwashers require a lower final rinse temperature because the chemicals used for sanitization work effectively at lower temperatures. The chemical solution is able to kill bacteria and viruses even at these lower temperatures, reducing the risk of contamination on the dishes. Other types of dishwashers, such as those using high-temperature sanitizing methods, require higher rinse temperatures to achieve the same sanitizing results.


Is there anything as isotherm in chemistry?

"Iso" means the same. "Therm" refers to temperature. An isotherm is an area which has the same temperature. Meteorologists use isotherms on maps to show us the weather patterns and temperatures in different areas. Temperature is one of the things you can study in chemistry. Other than that, I am not certain what you are actually asking.


What is the difference between diffusion potential and nernst potential?

The Diffusion Potential is the potential difference across the boundary b/w two electrolytic solutions of different compositions The Nernst Potential is the diffusion potential across a membrane that exactly opposes the net diffusion of a particular ion through the membrane

What is the difference between two temperatures?

The difference between two temperatures is the numerical value that represents how much one temperature is larger or smaller than the other. To calculate the temperature difference, you subtract the lower temperature from the higher temperature.


How does the temperature of the Earth's mantle compare to the temperatures of the other layers of the Earth?

Why should temperature be in kelvin in the equation pV equals nRT?

Most other temperature scales are not absolute - the lowest possible temperature is not zero.


Why is doubling the Celsius temperature a good approximation?

The equation for working out the temperature in fahrenheit from celsius is f = 9c/5 + 32 In other words, you multiply by slightly less than two, and then add more on. Therefore for many temperatures, just doubling would be a good approximation. Indeed, when the temperature is 160celsius, doubling would be correct.

Can two isotherm intersect each other?

No.An isotherm is a collection of points that are all at the same temperature. If two (different) isotherms were to touch each other then that would imply that they were at the same temperature but, by definition, if they have points on them at different temperatures then all the points on them must be at different temperatures.
