Chapter 20, Problem 77IAE

Interpretation Introduction

Interpretation:

The volume of ${\text{O}}_{\text{2}}\text{(g)}$ in milliliters should be calculated which is measured at ${\text{24}}^{\text{o}}\text{C}$ and 757 mmHg, and released from solution in the first minute of the reaction if the reaction starts with 175 mL of 1.55 M ${\text{H}}_{\text{2}}{\text{O}}_{\text{2}}\text{(aq)}$ at t=0.

Concept introduction:

Rate of reaction is defined as the change in concentration of reactants or products with change in time.

$\text{Rate=}\frac{\text{-Δ[reactants]}}{\text{Δt}}=\frac{\text{+Δ[products]}}{\text{Δt}}$

Molarity is defined as the ratio of number of moles to the volume of solution in liters.

The mathematical expression is given by:

Molarity = $\frac{\text{number of moles}}{\text{volume of solution in L}}$
