Consider the Reaction CO(g)+ 2H₂(g)
CH₃OH(l)at 25°C $\Delta$

question 114

Short Answer

Consider the reaction CO(g)+ 2H₂(g)
CH₃OH(l)at 25°C.
$\Delta$ G°_f (CO)= -137.3 kJ/mol
$\Delta$ G°_f (CH₃OH)= -166.3 kJ/mol
$\Delta$ H°_f (CO)= -110.5 kJ/mol
$\Delta$ H°_f (CH₃OH)= -238.7 kJ/mol
S°(CO)= 197.9 J/K·mol
S°(CH₃OH)= 126.8 J/K·mol
Calculate $\Delta$ G° at 25°C.

Definitions:

Relevant Range

The span within which the assumptions about fixed and variable cost behaviors are valid.

Absorption Costing

An accounting method that includes all manufacturing costs - direct materials, direct labor, and both variable and fixed manufacturing overhead - in the cost of a product.

Variable Costing

An accounting method that only includes variable production costs (materials, labor) in product cost, excluding fixed costs.

Mixed Cost

A cost that has both fixed and variable components, which changes with the level of output but not in direct proportion.
