Chapter 11, Problem 141E

Interpretation Introduction

Interpretation:

The percent change in pressure when the reaction goes to completion should be determined.

Find out the change in pressure when following chemical reaction take place.

A(g)+2B(g)→2C(g)

Initial volume of A=1.5L and initial volume of B=2.0L. The total volume and temperature remain constant till the completion of the reaction.

Concept introduction:

Chemical reaction is a process that involves rearrangement of atom or ion, this leads the formation of new chemical molecules/ion. During chemical reaction number of atom of each element is conserved but number of molecules may change. During chemical reaction mass is also conserved.

Ideal gas equation

PV=nRT

$\frac{\mathrm{P}}{\mathrm{n}}$=constant(T and V not change
