1. Determine the factors that influence reaction rate 2. What the relation about the factor that influence reaction rate with rection
rateexplain it 3.
From this experiment data: For reaction: A + B
1. The factor that influence reaction rate are: a. Surface area
b. Concentration c. Temperature
d. Catalyst 2. a. the relation between surface area with reaction rate:
the reaction rate became faster, if the surface area is wider b. the relation between concentration with reaction rate:
the reaction rate became faster, if the concentration is bigger c. the relation between temperature with reaction rate:
the reaction rate became faster, if the temperature is higher d. the relation between catalyst with reaction rate:
the reaction rate became faster, if using catalyst at this reaction 3. a. exp. 1: 5 gram powder, B: 0.1 M, t: 2 second, T: 25
o
C exp. 3: 5 gram solid, B: 0.1 M, t: 5 second, T: 25
o
C from this data, we know that at exp. 1 and 2, have a difference in the form of
substance and time. So, can know that the factor that influence reaction rate is surface area.
Because the surface area from exp.1 is wider than exp. 2. And can causing the time of reaction exp. 1 is faster than exp. 2
b. exp. 2: 5 gram solution, B: 0.1 M, t: 2 second, T: 25
o
C exp. 4: 5 gram solution, B: 0.2 M, t: 1.5 second, T: 25
o
C from this data, we know that at exp. 2 and 4, have a difference in the
concentration and time. So, can know that the factor that influence reaction rate is concentration.
Because the concentration from exp.2 is bigger than exp. 2. And can causing the time of reaction exp. 2 is faster than exp. 4
c. exp. 3: 5 gram solid, B: 0.1 M, t: 5 second, T: 25
o
C exp. 5: 5 gram solution, B: 0.2 M, t: 1.5 second, T: 35
o
C from this data, we know that at exp. 3 and 5, have a difference in the form of
substance, concentration, time, and temperature. So, can know that the factor that influence reaction rate is form of substance,
