What is a rate law? A. An equation that relates the rate of a reaction to the equilibrium
position
B. An equation that relates the reaction rate to the concentrations of
the reactants
C. An equation that relates the rate constant to the temperature of a
reaction
D. An equation that relates the concentrations of reactants to the
rate constant

B

Explanation:

The rate law is a way for us to measure the rate of a given reaction by comparing it to the concentration of the reactants. Based on the mole ratios of the reactants, we can hypothesize that adding more reactant will speed up the rate of reaction due to the simple principle that if there is more of an opportunity for molecules or atoms to collide, then the rate of reaction will be faster. Hope that helps :)

2fe + 3h2so4 -> fe2(so4)3 + 3h2

it is necessary to balance equations in order to get the proper amount of reactants as well as products in order not to make a miscalculation.

you cannot change the subscripts as that would change the substance itself. for instance, diatomic elements such as h2 only have the subscript two when a gas. another example would be so4, if you were to change the subscript, the element would no longer be sulfate.

we change the coefficients instead as that only changes the number of molecules rather than the substance itself.

hope this !

d.) circle motion requires a force to give it a centripetal acceleration.
