At room temperature and pressure (RTP), what is the temperature in Kelvin?

• A. 273 K
• B. 298 K
• C. 310 K
• D. 250 K

Answer: (B)

At room temperature and pressure (RTP), the commonly accepted temperature is approximately 298 Kelvin. This value is significant because it corresponds to standard laboratory conditions, which provide a consistent reference point for various chemical experiments and calculations. When converting temperatures from Celsius to Kelvin, the formula used is K = °C + 273. Therefore, room temperature, which is generally regarded to be around 25 degrees Celsius, converts to 298 Kelvin when you add 273. This is why 298 K is considered the standard for RTP, making it the correct answer. Understanding the significance of 298 K is crucial in chemistry as it helps in calculating gas laws, reaction rates, and many other thermodynamic properties where standard conditions are assumed.
