Question

( 50,+frac{1}{2} 0,200 )
( t=0 quad 10 ) mole 15 mole 0
( t=t^{prime} quad 2 ) mole 11 mole ( quad 8 ) mele
2 moles of ( 80_{2} ) and 11 moles of ( D_{2} ) hid not enter the combination

# When a mixture of 10 moles of so, and 15 moles of O, was passed over catalyst, 8 moles of so, were formed. How many moles of SO, and O, did not enter combination respectively? (1) so, = 2 mol (2) So, = 8 mol (3) 0,= 2 mol (4) 02 = 12 mol 2

Solution
