Two gaseous compounds, A and B are introduced into an evacuated reaction chamber. The resulting reaction is exothermic and the balanced chemical equation is shown below.
A(g) + B(g) ---> C(g)
As A and B are initially introduced into the reaction chamber, which statement about the rates of the reaction is true?
(A) The rates of the forward and reverse reaction are the same.
(B) The rate of the forward reaction is faster than the rate of the reverse reaction.
(C) The rate of the forward reaction is slower than the rate of the reverse reaction.
(D) The rate cannot be determined without knowing the rate laws.
For this reaction:
Pa(s) +3 02 (g) - POg (s) + heat
Which of the following changes would INCREASE the initial rate of the reaction? More than one answer may be correct. Select all that apply.
O Grind the solid phosphorus into a fine powder
O Use more 02 (g) in the reaction mixture
Heat the reaction to a higher temperature
O Add an appropriate catalyst
Increase the volume of the reaction vessel
Hydrazine, a rocket propellant, can be made from its elements according to this reaction:
8 H2 +
3 N2
N2H4 + 4 NH3
(ammonia is also made)
