Question

[06.05]Which is not true regarding reaction rates?

During reactions, concentrations of all reactants decrease at the same rate.

Reaction rates decrease as the concentration of reactants decrease.

Catalysts are not used up in the reaction.

Catalysts speed up reactions by lowering the activation energy.

Answer 1

@Abhisar

Answer 2

What do u think it should be ?

Answer 3

uh well i am kinda stuck..
I know the answer isn't the last one because Catalyst do speed up reaction rates.

Answer 4

is the answer ? ;p

Answer 6

yes. because it's not so ;p

Answer 7

Alrighty, I' ll go with it. Thanks ! 😊

Answer 8

\(\sf 2H_2+O_2\Rightarrow 2H_2O\)
For each mole of \(\sf O_2, 2~moles~of~H_2\) is being consumed so rate is different

Answer 9

Consumed?

Answer 10

That means 2 moles of H2 is decreases for one mole decrease in O2

Answer 11

I see what you're saying now! Thanks again!!
