Multiple Choice
Which of the following correctly represents the values for standard temperature and pressure (STP) in chemistry?
A
273 ext{ K} and 2 ext{ atm}
B
25^ext{o}C and 1 ext{ atm}
C
0^ext{o}C and 760 ext{ mmHg}
D
0^ext{o}C and 1 ext{ atm}
Verified step by step guidance1
Understand that STP (Standard Temperature and Pressure) in chemistry is a set of conditions commonly used as a reference point for experiments and calculations involving gases.
Recall the standard temperature at STP is defined as 0 degrees Celsius, which can be converted to Kelvin using the formula \(T(K) = T(^\circ C) + 273.15\).
Recognize that the standard pressure at STP is 1 atmosphere (atm), which is equivalent to 760 millimeters of mercury (mmHg) or 101.325 kilopascals (kPa).
Evaluate each option by comparing the given temperature and pressure values to the standard values: 0 \(^\circ\)C (or 273 K) and 1 atm (or 760 mmHg).
Conclude that the correct representation of STP is the one that states 0 \(^\circ\)C and 1 atm, as this matches the universally accepted standard conditions in chemistry.
