Is photosynthesis an endothermic or exothermic process.

Endothermic; light energy is absorbed.

Endothermic; light energy is released.

Exothermic; light energy is absorbed.

Exothermic; light energy is released.

Chemists believe that chemical reactions occur because the molecules involved in the reaction

collide with each other with enough energy to break chemical bonds and arrange to form new products.

exist only below a certain maximum temperature.

are moving so fast that the chance of interaction is very small.

How does the presence of a catalyst increase reaction rate?

A catalyst decreases the activation energy.

A catalyst increases the activation energy.

Collision theory predicts all of the following EXCEPT that:

a reaction will occur if the reactants DO NOT collide

a reaction will occur only if the collision geometry is correct

a reaction will not occur if the collision occurs with energy that is less than the activation energy

frequency of collisions will increase with increasing temperature

Which of the following will have the fastest reaction rate?

methane gas because gases are more reactive than solids and liquids

salt because solids are more reactive than liquids or gases

water because liquids are more reactive than solids and gases

all of these will react at the same rate
