Which set of values represents standard pressure and standard temperature ? (1) 1 ATM and 101.3K (2) 1 kPa and 273K (3) 101.3 kPa and 0 C. (4) 101.3 atm and 273 C

Respuesta :

Standard temperature and pressure are 0°C and 1 atmosphere, and of course their equivalents in other units. 0°C=273K, 1 Atm = 101.3 KPa.

From the choices given, the correct answer is (3)

The set of values that represents standard pressure and standard temperature is (3) 101.3 kPa and 0 °C.

The standard state comprehends a set of conditions that are defined by convention.

  • The standard pressure is 1 atm, or what's the same, 101.3 kPa.
  • The standard temperature is 0 °C, or what's the same, 273.15 K.

At standard pressure and temperature (STP),  1 mole of an ideal gas occupies 22.4 L.

The set of values that represents standard pressure and standard temperature is (3) 101.3 kPa and 0 °C.
