Question

which statement best applies collision theory to preventing a dangerous reaction from occurring?
store the reactants together at a low pressure.
keep all sparks or flames away from the reactants.
store the reactants together at a low temperature.
keep the reactants in separate containers.

Explanation:

Collision theory states that for a reaction to occur, reactant particles must collide. Storing reactants in separate containers prevents reactant particles from colliding (as they are not in the same space), thus preventing the reaction. Storing together at low pressure/temperature or keeping sparks away don't directly prevent collisions as effectively as separating reactants.

Answer:

D. Keep the reactants in separate containers.
