that mean the particle will move automatically until equilibrium achieved?

what are the reaction that do not go faster even if we increase the concentration? How and why this occur?

what caused the water or other substance move down the concentration gradient? Is it a force or others?

Chemistry / Re: Why does a gas passed into water form bubbles?

When I doing an experiment that study the effect of temperature on the rate of reaction, I used a delivery tube to transfer the gas produced to another test tube that filled with distilled water. The bubble formed. It looked like the water form a membrane around the gas.How this formed? [
