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. - CORRECT
ANSWER-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 - CORRECT ANSWER-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? - CORRECT ANSWER-False
H2(g) + MgC03 (s) <---> H20(g) + Co2(g)
, 3A(g) + 2B(g) --> 2C(g)
at 100 degrees celcius, a mixture of these gases at equilibrium
showed that [A]=.855 M [B]=1.23 [c]=1.75 M. What is the
value of Kc for this reaction? - CORRECT ANSWER-3.24
write the Qc for the following chemical reaction
Fe3+ (aq) + 3OH- (aq) <---> Fe(OH)3(s) - CORRECT ANSWER-
1/[fe3+][OH-]^3
The reaction system
POcl3 (g)<---> Pocl (g) + cl2 (g)
is at equilibrium. what happens to the system when Pocl is
added to the container?
