Now, let's say at time is equal to 0 we're starting with an So this is our concentration The rate law was rate = k [D] [F] 2. So the concentration of chemical "A" is denoted as: \[ \left [ \textbf{A} \right ] \\ \text{with units of}\frac{mols}{l} \text{ forthe chemical species "A"} \], \[R_A= \frac{\Delta \left [ \textbf{A} \right ]}{\Delta t} \]. This means that $-\frac{\Delta [A]}{\Delta t}$ will evaluate to $(-)\frac{(-)}{(+)} = (-) \cdot (-) =(+)$. It is common to plot the concentration of reactants and products as a function of time. Reactants are consumed, and so their concentrations go down (is negative), while products are produced, and so their concentrations go up. The best answers are voted up and rise to the top, Not the answer you're looking for? Answer 12: The unit of measure for the rate of disappearance is concentration/time.
