Instantaneous Rate

[Giselle Littleton 1F]

How does the instantaneous rate react as the reaction proceeds?

[805394719]

The instantaneous rate decreases as the reaction proceeds because the reactants are consumed and less amount of reactant is left in the reaction which causes the rate of the reaction to decrease since the number of collisions between the reactants decreases and the change in the reactant concentration becomes less which causes the tangent to the plot of its concentration against time to become less steep as the reaction proceeds since the rate has decreased and the plot started to approach a straight vertical line as the reactant concentrations remain unchanged at equilibrium.

If you look at the curve graph for the concentration v. time, you can tell that the rate is very quick at first when the concentration is high and decreases as time increases.

The rate is high as the reaction begins because there are more reactants, as the concentration of reactants decreases, the rate decreases.

[AGaeta_2C]

Instantaneous rate decreases as time increases

[Hussain Chharawalla 1G]

I believe instantaneous rate becomes 0 when the reaction reaches equilibrium

[Adriana_4F]

Instantaneous rate decreases as time increases and becomes 0 when equilibrium is reached

[305385703]

The instantaneous rate of change decreases as the reaction proceeds. The reaction gets closer to equilibrium and so the rate decreases.

[805422680]

The rate is very high when the reaction starts and decreases as the reaction continues. This can be determined by the slope of the tangent line at that point of the curve

[Sara Richmond 2K]

Instantaneously was rate decreases with time. If you think about it, it makes sense that the reaction would slow as more of the reactants have been used up;.

[John Liang 2I]

looking at it graphically, the curve downwards will make the line tangent to the curve less and less steep. since the instantaneous rate is dependent on the slope of the tangent line, it will decrease over time. hope this helps

[Ruby Richter 2L]

Is there a case where the instantaneous rate increases with time?

[Shivam Rana 1D]

The instantaneous rate should decrease with time.

[CameronDis2K]

As the reaction proceeds, think of it as a curved graph (seen with the equilibrium reaction graph, with E), the initial rate is very high as there is a readily amount of reactant available to react, and as its used up less reactant is available, so the reaction rate goes down (as reaction rate depends on concentration of reactants), eventually it will level out when all the products are formed (curved graph situation).
