please help!

Is RTP in chemistry (thermochemistry and electrochemistry) referring to room temperature of 25degreeC (or 298K) and 1atm, or 20degreeC (293K) and 1atm?

In my lecture notes on gas law, they stated RTP refers to 25degreeC, but in my electrochem lecture notes they mentioned specifically that rtp is 20degreeC.

What???

Please please please help! Thanks! I tried googling but i got even more confused.

Here is a link to read that will show the confusion. Both 20 C and 25 C are used.

I understand that you're confused about the reference temperature and pressure (RTP) in chemistry, specifically in thermochemistry and electrochemistry. Let me help you clarify this.

RTP, or reference temperature and pressure, is used as a standard condition to compare and measure various properties in chemistry, including thermochemistry and electrochemistry. However, the specific values for RTP can vary depending on the context and the discipline within chemistry.

In the case of thermochemistry, RTP typically refers to a temperature of 25 degrees Celsius (298 Kelvin) and 1 atmosphere of pressure. This is commonly used as a standard reference condition for many thermochemical calculations.

On the other hand, in electrochemistry, RTP can refer to a slightly different set of conditions. It is often defined as a temperature of 20 degrees Celsius (293 Kelvin) and 1 atmosphere of pressure. This particular set of conditions is used to standardize electrochemical measurements and is commonly referred to as the "standard temperature and pressure" (STP) conditions.

So, to summarize, in thermochemistry, RTP usually means 25 degrees Celsius (298 Kelvin), while in electrochemistry, RTP typically refers to 20 degrees Celsius (293 Kelvin). The different values reflect the varying conventions and standards used in these different branches of chemistry.

If you encounter conflicting information in your lecture notes or other sources, it's important to refer to the specific context in which RTP is mentioned. This will help determine which set of conditions is being referred to. Additionally, consulting with your instructor or classmates can also provide further clarification on the specific conventions used in your course.

I hope this explanation helps clear up your confusion!
