Reaction Rate

Question 1 • FL-2003350-Chemistry 1 Honors

Fill in the blanks to formulate hypotheses to both parts of the lesson question - what is the effect of temperature on reaction rate, and what is the effect of a reactant’s particle size on reaction rate?Hypothesis 1 (Temperature): If you increase the temperature of a reaction,then the reaction rate will because particles experience

Answer
A
decrease
B
increase
C
fluctuate
D
not change

Explanation

Increasing temperature gives reacting particles more kinetic energy, so they move faster and collide more often and with greater energy. This generally increases the reaction rate, so the blank is “increase.” The correct choice is B, increase.
