Increasing the concentration of a reactant shifts the position of a chemical equilibrium towards formation of more products. what effect does adding a reactant have on the rates of the forward and reverse reactions?

a)There is no effect
b)Both the forward and reverse speed up by same amount
c)The foward reaction speeds up immeditaly
d)Forward reaction slows down
e)the forward reaction speeds up
f)more info needs to be given.

The required "option is e)".

Explanation:

The Rate of formation of products depends on the concentration of reactants or the forward reaction increases on increasing the rate of the concentration.There is no effect on the equilibrium rate when the concentration of reactants and products is constant.Forward reaction slows down when the reactant concentration is decreased.On increasing the amount or concentration of reactant the chemical  equilibrium shifts towards formation of more products.Hence, the forward reaction speeds up.

The independent variable is the type of music.the dependent variable is the pulse rate.the intervening variable is the age of the subject.if the mother does not like rock, her pulse is likely to not increase.the same might be true for the sister.the friend may like rap and gets excited.to establish cause/effect relationship, all of the subjects must be consistent.hope i .
