Concept introduction: Rate of a chemical reaction : It tell us about the speed at which the reactants are converted into products. Mathematically, rate of reaction is directly proportional to the product of concentration of each reactant raised to the power equal to their respective stoichiometric coefficients. Let’s say we have a reaction: aA+bB → cC+dD then, rate α [A] x [B] y ⇒ rate =K f [A] x [B] y where K f = constant x and y are order of reaction with respect to A and B

Solution Summary: The author explains that the rate of a chemical reaction is directly proportional to the product of concentration of each reactant.
Definition Definition Number that is expressed before molecules, ions, and atoms such that it balances out the number of components present on either section of the equation in a chemical reaction. Stoichiometric coefficients can be a fraction or a whole number and are useful in determining the mole ratio among the reactants and products. In any equalized chemical equation, the number of components on either side of the equation will be the same.

Interpretation Introduction
(a)
Interpretation:
To determine the test tube which has the smallest rate.
Concept introduction:
Rate of a chemical reaction: It tell us about the speed at which the reactants are converted into products.
Mathematically, rate of reaction is directly proportional to the product of concentration of each reactant raised to the power equal to their respective stoichiometric coefficients.
Let’s say we have a reaction:
aA+bB→cC+dDthen,rateα[A]x[B]y⇒rate=Kf[A]x[B]ywhereKf=constantx and y are order of reaction with respect to A and B
Interpretation Introduction
(b)
Interpretation:
To determine the change in the value of rate constant and activation energy when temperature is increased.
Activation energy is the amount of energy required to reach the transition state. It is independent of temperature. Catalyst are generally added to chemical reaction to decrease activation to make reaction faster or even slower.
The heat of combustion for ethane, C2H6C2H6 , is 47.8 kJ/g. How much heat is produced if 1.65 moles of ethane undergo complete combustion?
