The more concentration on the reactants, the greater the pressure. both these things mean more effective collisions and faster reaction rates.

What's the question.

dtan5457 · Answer

Is my statement correct? Basically the more concentrated the reactants, the greater the pressure?

thadyoung · Answer

Well, yes. You can think about it by thinking about the ideal gas law (assuming ideal gas, not real)
If you have a syringe containing 100 cm$^3$ of a gas and press the plunger down to the 80 cm$^3$ mark, you have increased the pressure of the gas. You have also increased its concentration, as you have the same number of gas particles, but now they are in a smaller volume. Does that make sense?

thadyoung · Answer

When those gases react, by increasing the pressure, you als increase the rate of the reactio (which you have said) because of collision.

Got it, thanks.
