What is the typical temperature of interest used for calculating delta H's? Thank you!!

Professor Lavelle mentioned to us that we should assume that the temperature of reactions would be 25 degrees Celsius unless stated otherwise.

For an element, it is the most stable at 1 atm and the temp of interest is usually 25 celsius

298 Kelvin is also useful.

I believe it is 25 degrees celsius, unless the problem says differently

25 Celcius plus 273 to get the kelvin
