Adding a catalyst as this would speed up the reaction and the rest would slow it down
Answer:
A. The conditions are:
I. Reactant particles must collide with the right orientation.
II. There must be effective collisions.
III. The reactant particles must possess enough energy to break old bonds so that new bonds can be formed.
B. The activated complex occurs where the maximum energy of the reaction is attained along the reaction pathway, that is, at the peak of the activation energy.
Answer:
V2 = 35.967cm^3
Explanation:
Given data:
P1 = 0.2atm
P2 = 1.4atm
V1 = 250cm^3
V2 = ?
T1 = 10°C + 273 = 283K
T2 = 12°C + 273 = 285K
Apply combined law:
P1xV1/T1 = P2xV2/T2 ...eq1
Substituting values:
0.2 x 250/283 = 1.4 x V2/285
Solve for V2:
V2 = 14250/396.2
V2 = 35.967cm^3
