🤓 Based on our data, we think this question is relevant for Professor Rider's class at WWU.

# Solution: Is the rate of disappearance of reactants always the same as the rate of appearance of products?

###### Problem

Is the rate of disappearance of reactants always the same as the rate of appearance of products?

###### Solution

We’re being asked to calculate the to determine if the rate of disappearance of reactants always the same as the rate of appearance of products.

Recall that the average rate of a reaction is given by:

$\overline{){\mathbf{Rate}}{\mathbf{=}}\frac{\mathbf{∆}\mathbf{\left[}\mathbf{A}\mathbf{\right]}}{\mathbf{∆}\mathbf{time}}}$

where Δ[A] = change in concentration of reactants or products (in mol/L or M) and Δtime = change in time
