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 is caused when critical mass is reached?
a chain reaction
Does a reaction take place if the energy of the collision is greater than or equal to the activation energy?
no
What is required for a chain reaction to start?
Critical Mass is that minimum amount of fissionable material needed to maintain a chain reaction
How does reaction time affect reaction distance?
Because it you a slow reactionist, then it effects the time when you do react. For example, a car is coming at you and you react quickly. You reaction distance will be better that when you react a couple seconds later.
When will a collision lead to a chemical reaction?
When the collision is hard and fast enough. Increasing the kinetic energy will increase the likelihood of hard and fast collisions, which will ultimately increase the rate of the reaction. (This is called collision theory.)
How does the factor concentration affect reaction rate?
increasing concentration increases rate of reaction as there are more particles so there is a larger chance of collision,it increases the probability of collision of the reactants.
How does concentration factors affect reaction rate?
increasing concentration increases rate of reaction as there are more particles so there is a larger chance of collision,it increases the probability of collision of the reactants.
What is a vehicle's reaction distance?
Reaction distance is the distance a vehicle will travel before the operator can react to what is observed. This distance will vary depending on the speed of the vehicle. The reaction distance is actually the reaction time of the operator.
What are the release dates for Reaction and Review - 2011 Collision Course 1-6?
Reaction and Review - 2011 Collision Course 1-6 was released on: USA: 4 April 2011
When talking about physical science what is the collision theory?
Collision theory is an instance of reaction kinetics. It serves as occurences of the topic map.
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.
Perception distance plus reaction distance plus braking distance is called?
Stopping Sight Distance
What is your vehicle reaction distance when travelling at 40 mph?
The vehicle's reaction distance depends on the driver's reaction time.
What is the amount of fissionable material required to continue a reaction at a constant rate?
At less than critical mass, there are fewer "targets" for neutrons to strike, fission, and release more neutrons. As a result, the reaction dies out.
What is reaction distance?
reaction distance is the distance travelled from the time you see and analyze a threat, to the time you actually physically react.
What is a reaction distance?
Reaction distance is the distance a vehicle travels from the moment a driver perceives a hazard until they physically react by applying the brakes or taking other evasive action. It is influenced by factors such as speed, driver alertness, and road conditions.
