Interpretation:
The conditions when real gas behaves as ideal gas needs to be explained.
Concept introduction:
This is based on kinetic molecular theory of gases.
Answer to Problem 33SSC
Real gas behaves as ideal gas at high temperature and low pressure.
Explanation of Solution
According to kinetic molecular theory, a gas which is ideal follows:
- Volume occupied by a molecule should be negligible as compared to total volume of gas.
- There should be no attractive forces between the gas molecules.
So, a real gas can behave ideally if above postulates are followed and these can be followed if temperature is high and pressure is low. These conditions will help the gas particles to remain at larger distance with no attractions.
High temperature and low pressure are necessary to behave a real gas ideally.

An engineer proposes using this half-reaction at the anode of a galvanic cell that must provide at least 1.10 V of electrical power. The cell will operate under standard conditions. Note for advanced students: assume the engineer requires this half-reaction to happen at the anode of the cell. Is there a minimum standard reduction potential that the half-reaction used at the cathode of this cell can have? If so, check the "yes" box and calculate the minimum.
