Answer:
Explanation: As with any substance, oxygen takes up much less space as a liquid than it does as a gas, so engineers can fit more oxygen into the same tank.
<span>CH4 will effuse the fastest.
The speed of effusion is proportional to the speed of the gas molecules with faster molecules effusing fast than slower molecules. And the speed of the molecules at any given temperature is inversely related to the mass of the molecules with lighter molecules being faster. So let's take a look at the mass of the candidate molecules and see which is lighter and therefore faster.
CH4 - Molar mass is about 16.
CO - Molar mass is about 28
Ar - Molar mass is about 40
CO2 - Molar mass is about 44
If the 4 options, CH4 (methane) is by far the lightest, and therefore the fastest, so will effuse faster than the other 3 gasses.</span>

Answer:
The correct option is;
f
Explanation:
Here we have the activation energy is the minimum energy that is needed to allow a reaction to take place. The activation energy is the energy atoms or molecules need to be in a state where they can take part in a chemical reaction or a physical transport.
In the diagram, It is the amount of energy to be added to the energy in the reactants in their initial state which is on the left plateau on the reaction-energy chart, to the transition state which is the peak of the chart.
