Why do reaction rates slow as time goes on?

Answer 1

There are fewer reactants left to collide.

Answer 2

There are fewer reactants left to collide.

Answer 3

There are fewer reactants left to collide.

Answer 4

Many possible reasons.

One or both the reactants may have run out.

The reaction may be an equilibrium reaction in which equilibrium has been reached.

The reaction may be endothermic and heat energy is being used up.

Answer 5

they slow as you get older because of things such as your aterie lose elasticaton

bones more bitle

worse eyesight

tighter muscles

your best reaction time is in your prime

Answer 6

(Explanation): simply, there are less reactants left to create more products, so the rate at which the reaction occurs goes down. a helpful analogy would be that there are less apples to make apple pie with, so the production of apple pies goes down.

Answer 7

As a reaction progresses, the concentration of reactants decreases, leading to fewer collisions between reacting molecules. This decrease in collisions reduces the frequency of successful collisions, ultimately slowing down the reaction rate. Additionally, as the reaction proceeds, the formation of products can create an equilibrium that inhibits further forward progress.

Answer 8

Because the concentrations of reactants decrease.

Answer 9

There are fewer reactants left to collide.
