At a higher concentration of sulfuric acid magnesium collides with higher chance of collision which is why it leads to greater reaction rate.

1 answer

Your statement is partially correct. The concentration of sulfuric acid does indeed affect the rate of reaction with magnesium. However, it is not necessarily due to an increased chance of collision between the two substances.

When the concentration of sulfuric acid is increased, there are more acid particles in a given volume, which means that there is a higher probability of acid particles coming into contact with the magnesium surface. This increased contact leads to a higher rate of reaction. Essentially, a higher concentration provides more acid particles that can react with magnesium, increasing the likelihood of successful collisions and speeding up the reaction.

It's important to note that the rate of reaction is not solely determined by collision frequency, but also by other factors like temperature, surface area, and the presence of catalysts.
