Question

in the formation of silicon carbide represented by the chemical equation SiO2+3C-->SiC+2CO,8.0 mole of each reactant are available for the reaction. What substance is the limiting reactant?

Answer 1

The limiting reactant : C

Further explanation

Limiting reactant : the smaller ratio from mol and their reaction coefficient

Reaction

SiO₂+3C⇒SiC+2CO

Reactants : SiO₂ and C

mol ratio

• SiO₂ :

$\tt \dfrac{8}{1}=8$

• C :

$\tt \dfrac{8}{3}$

$\tt \dfrac{8}{3}$
