Ok, I don't know if I'm missing something but, why would increasing/decreasing A or B affect the reaction rate of the irreversible reaction? Also, why would removing C NOT affect the reaction rate? Am I missing something and this question is really easier than it seems? Thanks in advance to those responding 🙂

remiving C will NOT affect the reactin rate since it is the product of an irreversible reaction.

read the answer CAREFULLY, it is pretty claer.

U should know that by adding A or B or by changing the temp, u would effect the rate of the reaction foward, towards the product. However, since the reaction is irreversible that means it can't go from the products to the reactants C------- A+B, Therefore, the removing or the adding of C would not effect the reaction Rate. I really hope I was Clear, U definitely should read the solutions in the destroyer they are really clear and helpful. Good Luck studying.

i read the solution over and over but still do not understand. Maybe i"m just looking too much into it as usual or just am totally lost but can anyone help please?

Are you applying le chatlier's principle in your reasoning? If you are...go back and read what type of reaction this is...what type of reaction does le chatlier's principle apply to?

ah you're right I was using chatelier but that's for REVERSIBLE and we have an IRREVERSIBLE so that's why that doesn't work, right?

but then what are rules for irreversible rxns other than
-chaing reactants affects rxn rate
-adding catalyst or temp increase changes rxn rate
-removing product does not change rxn rate (cuz you can't go backwards)

please correct me if I'm still wrong and thank you so much for the help! 🙂
