1. Introduction
1.1. 실험 목적
회분식 반응기에서 에틸아세테이트의 분해 반응을 용액의 전기 전도도를 실시간으로 측정하여 회분식 반응기의 기초 몰 수지식을 활용하여 반응 속도 상수를 구해 낸다.
농도를 시간에 따라 측정한 후 자료 해석의 미분법 또는 적분법 중의 어느 하나를 이용하여 반응차수와 반응 속도 상수를 구한다.

1.2. 반응 속도식
1.2.1. 반응 속도식의 정의
다음의 균일계의 화학반응을 생각해 보자.
(1.1)
이 반응의 빠르기는 특정성분의 반응계 단위부피, 단위시간당 반응(소실 또는 생성)한 몰 수로 표시되며, [㏖/dm3·s]이다. 반응물질 A에 대해서는 시간적으로 감소하므로 -rA이며, 생성물질 R에 대해서는 rR로 나타내어지며, 이들 사이에 양론 계수를 이용해서
(1.2)
2개 이상의 상이 관계되는 불균일계 반응에서는 반응계의 부피 대신에 계 면적이나 촉매의 질량이 기준으로 사용되며, 기-고 촉매반응속도를 -rA′[㏖/g촉매·s], 기-액 계 반응속도는 -rA〃[㏖/㎡계면적·s]가 채용된다.

1.2.2. 반응차수
반응속도는 일반적으로 온도와 농도에 관계되며, 성분농도의 의존성은 실험적으로 정해진다. 이 의존성의 가장 일반적 형태의 하나는 각 성분의 농도의 곱으로써 다음과 같이 표시된다.
(1.3)
여기서 k는 온도에만 의존하는 반응속도상수이고, 농도항의 지수 α, β는 각각 A, B에 대한 반응차수라 부르며 총괄의 반응차수 n는 α+β의 합이다. 예를 들면 기상 반응 2 NO + O2 → 2NO2의 반응 속도는

NO에 대해서 2차, O2에 대하여 1차인 3차 반응이다. 또한 반응차수는 반드시 정수이지는 않다. CO + Cl2 → COCl2 의 반응에서는

때로는 반응속도가 다음과 같이 온도항과 농도항으로 구별 할 수 없는 경우도 있다.
