I think the answer is A.
A. the speed of the walkway multiplied by the speed at which she is walking
The speed she is walking accelerates her speed by the base speed of the walkway.
We see the order with respect to crystal violet (m),but no longer the order with respect to hydroxide (n).
<h3>Concentration of hydroxide ion equation</h3>
Generally the equation for the chemical reaction is mathematically given as
(CV)+(aq) + (OH)-(aq) ------------>. CVOH(aq)
The rate law for the chemical reaction is given as
Rate = k[CV+]m[OH-]n,
Because the hydroxide ion conc is an extra of thousand times as massive as the conc of crystal violet, [OH–] will now not exchange drastically all through this experiment.
Therefore, you will find the order with respect to crystal violet (m),but no longer the order with admire to hydroxide (n).
