Question

Hey guys! What is the rate constant is particularly sensitive to:

1 A change in volume
2 A change in pressure
3 A change in product concentration
4 A change in reactant concentration
5 A change in the activation energy

I feel like it is a change in the activation energy b/c the Arrenihus equation. I'm just unsure.

Answer 1

I agree with you from the choices given but I would choose temperature first if given that choice.

Answer 2

A 45.8 g sample of iron ore is treated as
follows. The iron in the sample is all converted
by a series of chemical reactions to Fe2O3.
The mass of Fe2O3 is measured to be 24.3 g.
What was the mass of iron in the sample of
ore?
Answer in units of g.
