The activity of an ideal gas is numerically __________ its pressure.

The activity of an ideal gas is numerically __________ its pressure. Correct Answer Equal to

Activity $$\left( a \right)$$ of a pure ideal gas is defined as:

$$a = \frac{{{\text{fugacity at an temperature and pressure of interest}}}}{{{\text{fugacity at same temperature and standard pressure }}}}$$

usually the, standard pressure $$=$$ 1 atm and for ideal gas fugacity at a temperature and pressure $$=$$ pressure at that conditions
So, $$a=P$$
