Expert Solution

Step 1

1) The standard state is defined as follows: for a gas, the pure gas at a pressure of exactly 1 atm (atmospheric). or 760 torr or 760 mmHg.

For a liquid or solid, the pure substance in its most stable form at a pressure of 100000 Pa (1 bar) and the temperature of interest (often taken to be 0 degree Celsius / 273.15 K).

and for the substance in the solution, a concentration of exactly 1 M (Molarity).
