A catalyst accelerates a reaction because:
A.) it decreases the number of molecules with energy equal or greater than the
activation energy
B.) it lowers the activation energy for the reaction
C.) it increases the number or collisions between molecules
D.) it supplies energy to reactant Molecules. - (answers)B.) it lowers the activation
energy for the reaction
Consider the Reaction:
8A(g) + 5B(g) --> 8C(g) + 6D (g)
If C is increasing at a rate of 4.0 M/s, at what rate is D changing?
A.) 4.9 M/s
B.) 3.0 M/s
C.) 2.0 M/s
D.) 6.0 M/s
E.) 4.0 M/s - (answers)B.) 3.0 M/s

A good catalyst will speed p the forward reaction but not affect the speed of the
reverse reaction.
True or False? - (answers)False
H2(g) + MgC03 (s) <---> H20(g) + Co2(g)
what will happen to the amount of volume in the container?
A.) Amount of carbon dioxide present will increase
B.) Amount of carbon dioxide present will decrease
C.) the amount of carbon dioxide will be unchanged
D.) the equilibrium constant will have to decrease to compensate
E.) More info is needed - (answers)A.) Amount of carbon dioxide present will
increase
2NaHCO3 (s) <---> Na2CO3(s) + H20(g) + Co2 (g)
