Consider the following representation where a and b are reactants.

a + b > products

which rate law correctly applies to this reaction?
k[a]

k[ab]

k[b]

k[a][b

Option (b) is the correct answer.

Explanation:

Rate law is defined as the concentration of reactants and products present in the chemical reaction.

Since, in an elementary reaction the stoichiometric coefficients are equal to the order of reaction.

For example, in the given reaction , the rate law of the reaction will be as follows.

Here the stoichiometric coefficients are 1 for both A and B.

Thus, the rate law that correctly applies to this reaction is K[A][B].

odds are decent that your handwriting right now looks a little bit different than it did five years ago, and will look different again in five more. when i look back through my notebooks from middle school to now, i see a long, slow progression from meticulous and teeny letters to bigger, sloppier ones, plus a few side detours: sometime in high school, for example, i decided those loopy cursive lowercase f’s were just the coolest, adopting them as the lone rep for cursive in my otherwise all-print handwriting.

explanation:

the answer is d.) potassium
