An enzymatic reaction is an equilibrium reaction and the determiners of rate include enzyme and substrate concentration. An increase in either enzyme or substrate concentration will increase the rate of the reaction until one or the other component becomes saturated, beyond its ability to react or be reacted at a higher rate.
Usually, increasing concentration of reactants increases the rate of reaction, but increasing concentrations of products reduces the rate of reaction. However, if one reactant is already present in large stoichiometric excess over another, increasing the concentration of that reactant may not increase the rate of reaction at all, and if the free energy of reaction is large enough in magnitude, increasing the concentration of products may not reduce the rate of reaction at all.
Increasing the concentraion the reaction rate increase.
The higher the substrate concentration, the higher the rate of reaction, up till the point when the limiting factor is no longer the concentration of substrate but other factors like enzyme concentration of temperature.
because the amount of the other variables are the same, no change. once 4.0 g of lactose substrate or whatever it is is at it's maximum reaction rate, it can do no one reaction therefore there was no reaction in the 8.0 g of substrate. Because the reaction volume was also doubled; so there was no change in concentration of substrate.

The rate of enzyme reaction is increased when the substrate concentration is also increased. However, when it reaches the maximum velocity of reaction, the reaction rate remains constant.
Increasing the concentration of the reactants the rate of reaction increase.

If the reaction speed has not already peaked, then it will increase
competitive inhibition
Increasing the concentraion the reaction rate increase.
increasing the concentration in a rate of reaction makes the reaction take place faster because if there is more initial particles then there is more particles to react
Increasing enzyme concentration increases the number of collisions between the enzyme molecules and the substrate molecules. This increases the number of successful collisions and the number of enzyme-substrate complexes. Therefore the reaction rate is increased as well and enzyme activity is promoted.
The higher the substrate concentration, the higher the rate of reaction, up till the point when the limiting factor is no longer the concentration of substrate but other factors like enzyme concentration of temperature.
The concentration of reactants is changed.
Yes. For this reason, increasing the concentration of the molecules involved increases the rate of reaction.
