Which is the limiting reagent when 100.0g of hexane C6H14(l) is reacted with 500.0 litres of oxygen gas at LTP, according to the reaction: 2 C6H14(l) + 19 O2(g) > 12 CO2(g) + 14 H2O(l)

(RAM H = 1.0, C = 12.0 and 1 mol of gas occupies 24.5 litres at LTP)

N C6H14 = 100/86 = 1,163 mol

n O2 = 500/24,5 = 20,41 mol

2 C6H14 + 19 O2 —-> 12 CO2 + 14 H2O
1,163          20,41        -                   –        n mula
1,163          11,0485     6,978        8,141    n reaksi
–                 9,3615                                   n akhir

n sisa = O2, jadi C6H14 adalah pereaksi pembatasnya
