Flow Charts for Chemical Synthesis (HSC SSCE Chemistry): Flashcards

Visual diagram showing step-by-step chemical production process

Iron(III) oxide ($\text{Fe}_2\text{O}_3$)

$\text{N}_2 + 3\text{H}_2 \rightleftharpoons 2\text{NH}_3$

Increases collision frequency between reactant molecules

Forms hydrogen bonds (high BP), unlike $\text{N}_2$ & $\text{H}_2$

Recycled back to beginning

High temp shifts equilibrium backwards, reducing $\text{NH}_3$ yield

Substances found in nature in usable form

$-92.4$ kJ mol$^{-1}$, exothermic

Chemical (unreacted materials) and energy (heat from reactions)
