Factors affecting the rate of chemical reactions.

The rate of chemical reactions is influenced by the state of aggregation of substances, temperature, pressure, concentration of reagents, surface areas for solid compounds, the presence of catalysts:
1. The higher the temperature, the faster most reactions are.
2. Pressure influences the predominant side of the reaction in gas synthesis (for example, ammonia)
3. The more thoroughly the substance is crushed, the larger the contact area, and, accordingly, the reaction rate
4. The higher the concentration of compounds, the higher the speed
