What are the 5 major reactions?

What are the 5 major reactions?

The five basic types of chemical reactions are combination, decomposition, single-replacement, double-replacement, and combustion.

What influences the rate of a reaction?

The rate of a chemical reaction is influenced by many different factors, including reactant concentration, surface area, temperature, and catalysts.

What are 5 pieces of evidence that a chemical reaction has taken place?

The five conditions of chemical change: color change, formation of a precipitate, formation of a gas, odor change, temperature change.

What has the greatest influence on reaction rate?

Temperature. Raising the temperature of a chemical reaction usually results in a higher rate of reaction. When the reactant particles are heated, they move faster and faster. Increasing the temperature of a reaction increases the number of effective collisions between reacting particles, so the reaction rate increases.

What are 3 factors that influence the reaction rate of a chemical reactions?

The factors that affect reaction rates are:

• surface area of a solid reactant.
• concentration or pressure of a reactant.
• temperature.
• nature of the reactants.
• presence/absence of a catalyst.

What six factors may influence the rate of a reaction?

The rate of a chemical reaction is affected by several factors like:

• Concentration of reactants.
• Pressure.
• Temperature.
• Catalyst.
• Nature of reactants.
• Orientation of reacting species.
• Surface area.
• Intensity of light.

What are the factors that affect the rate of reaction?

We can identify five factors that affect the rates of chemical reactions: the chemical nature of the reacting substances, the state of subdivision (one large lump versus many small particles) of the reactants, the temperature of the reactants, the concentration of the reactants, and the presence of a catalyst.

How do you find the rate of reaction?

Concentration => Rate = f (changing concentration of reactants and comparing rates of reaction) Area => Rate = f (surface area of reactant exposed to ignition source) Nature => f (changes in chemical composition of reagents in the reaction) Temperature => f (rates as a function of changing temperature conditions of the reaction system)

How does the presence of a catalyst affect a reaction?

The presence of a catalyst helps a reaction proceed more quickly to equilibrium. Aside from catalysts, other chemical species can affect a reaction. The number of hydrogen ions (the pH of aqueous solutions) can alter a reaction rate.

How does pH affect the rate of chemical reaction?

The number of hydrogen ions (the pH of aqueous solutions) can alter a reaction rate. Other chemical species may compete for a reactant or alter orientation, bonding, electron density, etc., thereby decreasing the rate of a reaction.
