Chapter 22, Problem 22.70P

(a)

Interpretation Introduction

Interpretation:

The balanced equation for photosynthetic reaction has to be written.

Concept Introduction:

Balanced Chemical equation:

A balanced chemical equation is an equation which contains same elements in same number on both the sides (reactant and product side) of the chemical equation thereby obeying the law of conservation of mass.

(b)

Interpretation Introduction

Interpretation:

The volume of oxygen gas required to fix carbon dioxide has to be calculated.

Concept Introduction:

  $\text{PV}\text{=}\text{nRT}$

Where,

  P is pressure

  V is volume

  n is number of moles

  R is gas constant

  T is temperature
