Answer» Correct Answer - B `NH_(3) (g)` `n = (PV)/(RT) = (1 xx 22.4)/(0.0821 xx 273 xx 2) = (1)/(2)` mole `HCl (g)` `n = (PV)/(RT) = (1 xx 44.8)/(0.0821 xx 54.6) = 1` mole `{:(NH_(3) (g),+,HCl (g),rarr,NH_(4)Cl(s),),((1)/(2),,1,,0,),(0,,(1)/(2),,(1)/(2),):}` `n_(HCl) = (1)/(2)` mole `P = (0.5 xx 0.0821 xx 546)/(67.2)` `P = (1)/(3)` atn |
