A student sets up two reactions. reaction 1 uses 0.170 mol/l of reactant, and reaction 2 uses 0.400 mol/l of reactant. how many times faster is reaction 2 compared to reaction 1?

In chemical reaction dynamics, the rate of the reaction can take different forms depending on the type. If we are to take this reaction as a first-rate reaction then, the rate is dependent to the concentration of the reactant.

n = 0.400 molL / 0.170 mol/L

n = 2.35 times

Thus, the second rate is 2.35 times the 1st rate.
