According to collision theory, what must the reactants have in order to form products?

• The right size
• The right shape
• Enough energy
• Nothing

Increase in temperature of the reactants can do one of the following

• Slow collision frequency
• Allow less effective collision between the particles
• Cause particles to lose speed
• Increase collision between the particles thus increasing the rate.
