2 questions

[Guest Kdawg]

I have two questions I need help with

1.) If a chemical reaction occurs at a rate of 2.25 10-2 moles per liter per second at 322 K, what is the rate expressed in moles per liter per minute?

2.) Which of the following does NOT affect reaction rate?

a.) concentration of reactants

b.) surface area of reactants

c.) reactivity of products

d.) catalysts

[DeoxyriboNucleicAcid]

for the second, i think you should just multiply that 2.25 10-2 thing by 60.

But im not quite sure, I have not taken chemistry yet.

2, im not sure about

It is the reactivity of the products. The catalyst speeds up the reaction and the surface area does so as well. The surface area causes more particles to be exposed to the reactants. This goes the same for the concentration
