In a reaction 3A + B, A,B, [NCERT Pg. 20]If 180 atoms of A and 100 molecules of B react,then1 B is limiting reactant and 100 molecules ofA, B, will be formed2 A is limiting reactant and 60 molecules of A,B2will be formed3 A is limiting reactant and 180 molecules ofA,B, will be formed​

Answer:in this reaction A is limiting reactant because for a molecule of B it requires 3 molecule of A so 100 molecules of B requires 300 molecule of A but it is only 180 molecules .so A is limiting reagent .so option 2 is correct bcs it forms only 60 molecules
