How is the effect of concentration changes on the reaction rate seen in the rate law?
A. The effect of concentration changes on the rate constant affects
the reaction rate.
B. The exponents determine how much concentration changes affect
the reaction rate.
C. The rate law does not show how concentration changes would
affect the reaction rate.
D. A change in concentration of a reactant would change the
exponent of that reactant.

1: Rate Laws. Typically, reaction rates decrease with time because reactant concentrations decrease as reactants are converted to products. Reaction rates generally increase when reactant concentrations are increased.

Explanation:

calculate how many grams of ammonia can be produced from 4.21 grams of

n2 + 3h2 = 2nh3

my answer:

25.0g n2 x (1 mol/ 28.0gn2) x (2 mol nh3/ 1 mol n2) x (17.0g nh3/ 1 molnh3) = 30.36g n2

25.0g h2 x (1 mol h2/ 2.00g h2) x (2 mol nh3/ 3 mol h2) x (17.0g nh3/ 1 mol nh3) = 141.67g h2

lr = n2
