Nitrogen dioxide is produced by combustion in an auto moles of nitrogen monoxide are mixed with 0.464 moles of oxygen gas. mobile engine. For the following reaction, 0.232 nitrogen monoxide(g) + oxygen(g) nitrogen dioxide(g) What is the formula for the limiting reagent? What is the maximum amount of nitrogen dioxide that can be produced? moles Retry Entire Group 4 more group attempts remaining

Explanation / Answer

the balanced reaction is given by

2 NO + O2 --> 2 NO2

now

moles of NO required = 0.464 moles 02 x 2 mol NO / 1 mol O2

moles of NO required = 0.928 moles NO

but

only 0.232 moles of NO are present

so

NO is the limiting reagent

2)

now

2 NO + O2 ---> 2 NO2

moles of NO2 that can be produced = 0.232 moles NO x 2 mol NO2 / 2 mol NO

moles of NO2 that can be produced = 0.232 moles NO2

so

0.232 moles of nitrogen dioxide can be produced
