## Factors Affecting k

$aR \to bP, Rate = -\frac{1}{a} \frac{d[R]}{dt} = \frac{1}{b}\frac{d[P]}{dt}$

### Factors Affecting k

Can the rate constant (k) of a reaction change? If so, how?

Yes, it can change if the temperature changes, that is the only way it can change

Yes, the rate constant can change. It can change due to temperature. The rate constant is related to temperature through the Arrhenius equation.

### Re: Factors Affecting k

k = A exp( -EA/RT )
this shows how it can be changed

### Re: Factors Affecting k

It can only change with temperatures.

### Re: Factors Affecting k

The rate constant k is similar to the equilibrium constant K in that it is only affected by a change in temperature.

temperature is the only way to change k

### Re: Factors Affecting k

Temperature can have an affect on the value of the equilibrium constant. This problem was also on the midterm i believe.

yes k can change, but only due to temperature.

Also, k is a intensive property, not an extensive property, right?

Generally, k increases with temperature.

### Re: Factors Affecting k

I believe we only go over temperature changing rate, however it can be changed by altering activation energy as well(adding or removing a catalyst)

It is related in the Arrhenius equation; k=Ae^(-Ea/RT)

I think we have to understand the concept of catalysts, but not necessarily how to compute an equation with them.

### Re: Factors Affecting k

The rate constant of the equation can alter in two ways: Changing temperature and addition of the catalyst. This can be considered as mixing salt into the water. If you add heat into the water, the molecules will vibrate even more which causes it to dissolve even more, and if you add some sort of proteins, it would be helpful to decrease the activation energy which means that because you don't need that much energy per reaction process, you can easily allow the equation to take place.

Isn't the addition of a catalyst also a way to change it?

### Re: Factors Affecting k

k can only change when there is a temperature change.
