Question

In order to measure the rate of a reaction, a chemist,

A. must measure the disappearance of all reactant substances

B. must measure the appearance of all product substances

C. must measure the disappearance of all reactant substances and the appearance of all product substances

D. can measure the disappearance of all reactant substances and the appearance of all product substances

The numerical value of the exponents in the rate of law (the order) is determined by

A. subtracting the sum of the product stoichiometric coefficients from the sum of the reacant stoichiometric coeffcient

B. looking at the stoichiometric coefficients of the reactants

C. experiment only

D. Looking at the stoichiometrix coefficients of the product

To measure only the forward rate of reaction, the concentration of t he reactants and/or products is measured_____

A. at any time during reaction

B. as close to the middle of a reaction as p ossible

C. at the very end of a reaction

D. at the very beginning of a reaction

Expert Solution

Step 1

The rate of reaction imeasures speed of a chemical reaction at which reaction take place.ItRate of reaction is proportional to the increase in the concentration of a product per unit time and to the decrease in the concentration of a reactant per unit time
