Consider a hypothetical reaction between a, b, and c that is first order in a, zero order in b, and second order in c.
(a) write the rate law for the reaction.
(b) how does the rate change when [a] is doubled and the other reactant concentra- tions are held constant

(a) Rate = k[A][C]²

(b) If [A] is doubled, then the rate of reaction will be doubled as well.

Explanation:

(a) The rate is equal to the multiplication of a constant and the concentrations of all reactants, each to the power of their order.

Rate = k[A]¹[B]⁰[C]² = k[A][C]²

(b) Looking at the previous equation we can see that if [A] is doubled, then the rate of reaction will be doubled as well.

if two electrons have the same n, the same ℓ, and the same ml, then they are in the same orbital. the pauli exclusion principle states that no two identical fermions (a fancy word for electrons and other subatomic particles like electrons) may occupy the same quantum state in an atom simultaneously.
