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

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.
