Question

what are the limiting and excess reactants to CO(g) + 2H2 - CH3OH if 1.55 moles of CO react with 1.22 moles of H2

Answer 1

CO + 2(H2) ----- CH3OH, this is the reaction we obtaine, now based on moles we have to find what hapen if we change the moles

1.55(CO) + 1.22(H2) ---- n(CH3) + m(OH)

We have:

1.55 C

1.55 O

2.44 H

And we need:

1 C

1 O

4 H

The difference are:

0.55 C, excess

0.55 O, excess

1.56 H, limiting
