What else can I help you with?
Molecules involved in a chemical reaction must collide to react What is this concept called?
This concept is called collision theory. It states that in order for a chemical reaction to occur, reactant molecules must collide with enough energy and proper orientation.
What are 3 conditions that necessary for a reaction to occur?
There are many factors that affect the occurance of a chemical reaction. If the reaction you are using has any buffer or catalyst than you should be selective in that keeping in mind your reactants and product. The temperature required for any particular reaction to occur should also be kept in mind.
What 3 things need to happen in order for a chemical reaction to occur?
This isn't answerable without knowing what the chemical reaction is. Some reactions are very easy to initiate - alkali metals and halogens will react with little to no prodding. Others require intermediate reactions.
Must particles collide in proper orientation for a reaction?
In general, for a chemical reaction to occur, particles must collide with sufficient energy and with proper orientation. The correct alignment allows the reacting molecules to approach each other in a way that their reactive sites come into contact, promoting the formation of new bonds and products.
What is collision model?
A Collision model is a model of the rate of a reaction showing how the rate is proportional to the number of collisions of reactant molecules.
What type of reaction occur when atoms combine to form molecules or when molecules break down into atom?
Chemical reactions.
What helps chemical reactions occur?
Chemical reactions occur when reactant molecules collide with enough energy and proper orientation to overcome the activation energy barrier. Factors such as increasing temperature, using a catalyst, and adjusting reactant concentrations can all help facilitate chemical reactions by providing more energy for collisions or altering the reaction pathway.
What does mean successful collision?
A successful collision occurs when two reactant molecules collide with enough energy and proper orientation to undergo a chemical reaction, leading to the formation of new products. This process is crucial for chemical reactions to occur in a timely and efficient manner.
What is the effect of a catalyst on the required energy to achieve effective collisions?
A catalyst lowers the activation energy required for a chemical reaction to occur by providing an alternative reaction pathway with lower energy barriers. This makes it easier for reactant molecules to collide effectively and react to form products.
What are the 2 reasons why a decrease in temperature slows a chemical reaction?
Decreasing the temperature reduces the kinetic energy of the molecules involved. This means that fewer molecules have the activation energy required to actually react. It also means that molecules will collide less often.
What happens when hydrogen and oxygen molecules form water?
A chemical reaction between oxygen and hydrogen occur.
What Protein are responsible for all chemical reaction that occur in cells - these proteins lock smaller molecules together and separate larger molecules?
Enzymes
