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.
When the volume of the reaction system is decreased, the equilibrium will shift towards the side of the reaction with fewer moles of gas to relieve the pressure. This causes the concentration of reactants to increase in order to establish a new equilibrium.
Increasing the concentration of reactants can increase the product rate by providing more molecules for the reaction to occur. Additionally, optimizing reaction conditions such as temperature, pH, and pressure can also increase the rate of product formation by favoring the reaction kinetics.
- Changing temperature (heating increases speed of endothermic reactions and such reactions with a huge activation energy; cooling increases speed of exothermic reactions - Adding a catalyst (makes the activation barrier smaller --> reaction faster) - Vary the pressure. If there are less equivalents of gas molecules on product site than on educt site, pressure increase will increase reaction speed and vice versa. - Changing concentration; if the educt concentration is increased or / and product concentration decreased (e.g. through destillation of the product), the reaction will go faster. --> These four principles can found in the Le Chatelier - Sentence. Nice example is the Haber-Bosch synthesis.
It leads to more frequent collisions, which increase reaction rate.
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.
Many factors can and do increase the rate of chemical reactions. The most obvious is an increase in temperature, although too large an increase can breakdown the reactants. Other factors include catalysts, enzymes, pressure, concentration of reactants , surface area and other forms of energy (UV is an example).
For most reactions which involve liquids or gases, increasing the concentration of the reactants also increases the rate of reaction. This is because the number of effective collisions are also increased which speeds up the reaction.

The equilibrium concentration of carbonic acid will increase because the system will shift to the right to relieve the increase in pressure by consuming more of the carbon dioxide to produce more carbonic acid. This shift helps maintain the equilibrium constant for the reaction.
The effect of concentration of reactants on rate of reaction depends on the ORDER of the reaction. For many reactions, as the concentration of reactants increases, the rate of reaction increases. There are exceptions however, for example a zero order reaction where the rate of reaction does not change with a change in the concentration of a reactant.
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.
Increased concentration, increased temperature, and a catalyst will all increase reaction rates relative to what they normally are. Some reactions however will still be slow even with the change in these variables.
