Chapter 9, Problem 9.67SP

Interpretation Introduction

Interpretation:

The amount of heat evolved or absorbed in the reaction have to be determined with the classification of the reaction as endothermic or exothermic

  $2Na(s)+2H_{2}O(l)\to 2NaOH(aq)+H_2(g)\Delta H^0=-368.4kJ$

Concept introduction:

The reaction or phase transition in which heat escape from the system to the surroundings are termed as exothermic, while the process in which the heat is absorbed by the system from the surroundings is called endothermic.

Given:

1.00g of Na reacts with $H_{2}O$.

To determine:

The amount of heat release or consume in the reaction and judgement of the reaction as exo-or endothermic point of view.
