Question
For cases where [A] exactly doubles:
• if the rate does not change, the order for A is 0.
• if the rate doubles, then the order for A is 1.
• if the rate quadruples, the order for A is 2.
For more complex cases, use the general equation:
order
rate₁
rate2
= (
[reactant],
[reactant]₂
What is the reaction order with respect to A?
Rate = K[A]orderA[B]orderB
[A], mol/L [B], mol/L rate, mol/(L-min)

Expert Solution
Step 1

The relation between the concentration of the reactants and the rate of reaction is expressed by the rate law. The rate law of a reaction is determined experimentally. The sum of the exponent term in the rate law for a chemical reaction is known as the order of the reaction.
