    Explain Kelvin
AI Thread Summary
The discussion revolves around converting a temperature change from Celsius to Kelvin. It clarifies that a change of 75°C is equivalent to a change of 75 K, as both scales have the same degree magnitude. The confusion arises from misunderstanding that the actual temperature is not needed for this specific conversion. The book's answer of 75 K is correct for the change in temperature. Therefore, the key takeaway is that temperature changes in Celsius and Kelvin are numerically equal.

A sample of liquid is heated from room temperature to just below the boiling point. The overall change in temperature is 75°C. Express this temperature change in kelvins.

The book has the answer as 75K. How did they arrive at that answer? I don't think I understand the problem. I rather converted from 75C to K and got 348 instead. Help please?

The change in temperature is 75 C, but the actual temperature is unknown. Since kelvin degrees and celsius degrees are the same magnitude, a change in temp. of 75 C is the same as a change of 75 K.

TL;DR Summary: cannot find out error in solution proposed. [![question with rate laws][1]][1] Now the rate law for the reaction (i.e reaction rate) can be written as: $$ R= k[N_2O_5] $$ my main question is, WHAT is this reaction equal to? what I mean here is, whether $$k[N_2O_5]= -d[N_2O_5]/dt$$ or is it $$k[N_2O_5]= -1/2 \frac{d}{dt} [N_2O_5] $$ ? The latter seems to be more apt, as the reaction rate must be -1/2 (disappearance rate of N2O5), which adheres to the stoichiometry of the...
