## Rate constant k

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

### Rate constant k

What is the conceptual idea for rate constant k in the equation? What does the rate constant k do?

### Re: Rate constant k

k quantifies the rate at which the chemical reaction occurs and allows us to determine the overall rate using the formula given. We multiply k to the molar concentrations of the reactants to their order number to find Rate.

### Re: Rate constant k

rate constant k determines how fast/slow the reaction occurs using the initial concentrations of the reactants

### Re: Rate constant k

To add on, the rate constant, k, does have different units depending on what order the reaction is. The general rule is as follows for the units of k: 1/(Mn-1*t-1), where n is the order of the reaction.
