- endothermic process
- exothermic process
- endergonic process
A: exothermic process

Q: A reaction where the products are higher in energy than the reactants is an example of an _____.

Q: Which of the following affects the rate of a reaction?
- concentration, temperature, nature of reactants, presence of solvents
- concentration, temperature, molecular size, presence of catalysts
- concentration, temperature, nature of reactants, presence of catalysts
A: concentration, temperature, nature of reactants, presence of catalysts

Q: What affect does temperature have on the rate of a reaction?
- the lower the temperature, the lower the kinetic energy which results in more effective collisions therefore increasing the rate of a reaction
- the higher the temperature, the greater the kinetic energy which results in more effective collisions therefore increasing the rate of a reaction
- the higher the temperature, the greater the kinetic energy which results in more effective collisions therefore decreasing the rate of a reaction
A: the higher the temperature, the greater the kinetic energy which results in more effective collisions therefore increasing the rate of a reaction

Q: Which statement best describes the effect of concentration on the rate of a reaction?
- higher concentrations result in more effective collisions therefore increasing the rate of a reaction
- higher concentrations result in less effective collisions therefore increasing the rate of a reaction
- higher concentrations result in more collisions therefore increasing the rate of a reaction
A: higher concentrations result in more effective collisions therefore increasing the rate of a reaction
