What is the collision theory and how does it relates to reaction rates?
it depends on how high or low the reactant is on the temperature.
What happens to the equilibrium concentration of reactants when the volume of the reaction system is decreased and why?
decrease in reactants and increase in products
What is the speed of a chemical reaction is increased by?
Most effectively increased speed by temperature increase and adding a catalyst ( = enzymes in biological reactions. Further measures: raising concentration of reactants, grinding solids, mixing, for some reactions: put in light scource
How are rates of reaction determine?
5 factors that can affect the rate of chemical reactions are temperature, pressure, concentration, stirring, catalysts, etc.
What are 4 things that affect the rate of a reaction?
1. The concentration of the substances. 2. The temperature. 3. The surface area of the particles. 4.The presence of a catalyst.
What would increase reaction rate?
raising the temperature of the reactants, by increasing their surface area, by increasing the concentration of reactants, by stirring the reactants, or by adding a catalytic agent can increase reaction rates
What is rate dependence on concentration of reactants?
The reaction rate increase with reactants concentration.
What are four ways that chemists can control chemical reactions?
increase in surface area, increase in temperature, increase the concentration of the reactants, and the presence of catalysts or inhibitors.
What conditions increase the rate of chemical reaction?
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).
What would increase the reaction rate?
raising the temperature of the reactants, by increasing their surface area, by increasing the concentration of reactants, by stirring the reactants, or by adding a catalytic agent can increase reaction rates
Which methods will usually cause a reaction to speed up?
Combining the reactants at a lower temperature. Reducing the concentration of reactants. Grinding one of the reactants into a powder. Removing the catalyst.
What is the collision theory and how does it relates to reaction rates?
it depends on how high or low the reactant is on the temperature.
Why would you increase the concentration of the reactants?
I dont know really
What happens to the equilibrium concentration of reactants when the volume of the reaction system is decreased and why?
decrease in reactants and increase in products
What change will most likely increase the rate of a chemical reaction?
Factors which can increase the rate of a chemical reaction:- temperature- pressure- concentration of reactants- stirring- if solids are involved the dimension of particles is important- the type of reaction- the order of reaction- presence of catalysts- influence of external factorsetc.
What is the effect varying the concentration on the rate of reaction time?
Increasing the concentration of the reactants the rate of reaction increase.
Does a change in the concentration of reactants result a change in temperature?
Sometimes this is possible.
