How can above reaction be classified in terms of energy exchange during chemical change?
2NaOH + H2SO4 → Na2SO4 + 2H2O
Given the following rate law,
rate = k[A]2[B]
if [A] were doubled, what must happen to [B] to keep the rate constant?
[B] must tripled
[B] must double
[B] must be havled
[B] must be quartered
The catalyst alters the rate of a chemical reaction by,
providing an alternative pathway with a lower Ea
changing the products formed in the direction of the reaction
providing a surface on which the molecules react
increasing the frequencies of collisions between molecules
The following data were measured for the reaction
BF3(g) + NH3(g) ⟶ F3BNH3(g)
What is the rate law for the reaction?
rate = k[NH3]
rate = k[BF3]2[NH3]
rate = k[BF3][NH3]
rate = k[BF3][NH3]2
What is the rate law for this mechanism?
rate = k[A][B]2
rate = [B][X]2
rate = [A]0.5[B]1.5
rate = [W][Y][Z]
Which factors increase the rate of a reaction?
increasing temperature
increasing concentration
increasing surface area
all of the above
What letter represents the activation energy?
A
B
C
D
What is the parameter to measure the rate or speed of a reaction beside time?
Change in volume
Change in concentration
Change in pressure
Change in temperature
Rate=[A]2[B]1
