Oooops!! It's general chem, not orgo! I am sorry.
The question is

A+B->C
which of the follwing woudl not affect the rxn rate of this irreversible rxn?
1) dec A
b) Inc B
c) Add a catalyst
d)Removing C
e) Inc T

no solid, aq, gas states. Just as it is. I thought the rxn is going from left to right if we remove C and it changes the rate of the rxn. But, orgoman says not. Anyone?

The forward reaction is bimolecular. any change in [A] or will modify rate. a catalyst would also change the rate of reaction. T usually increases rxn rate.

Remember that LeChat's principles of reaction equilibria deal with reversible reactions. In this case, any change in [C] will have no effect on the overall rxn rate because the reverse reaction, which is dependent on [C], does not occur. Irreversible is the key word.
