Vapour pressure of methyl alcohol and ethyl alcohol solutions is represented by `P = 115 x_(A)+140` where `x_(A)`is the mole fraction of methyl alcohol. The value of `underset(x_(A)rarr0)(lim)(P_(B)^(0))/(x_(B))` is:

At 40^(@)C , the vapour pressures in torr, of methyl alcohol and ethyl alcohol solutions is represented by the equation. P = 119X_(A) + 135 where X_(A) is mole fraction of methyl alcohol, then the value of underset(x_(A)rarr1)(lim)(P_(A))/(X_(A)) is

At 40^(@)C , the vapour pressures in torr, of methyl alcohol and ethyl alcohol solutions is represented by the equation. P = 119X_(A) + 135 where X_(A) is mole fraction of methyl alcohol, then the value of underset(x_(A)rarr1)(lim)(P_(A))/(X_(A)) is

The value of underset(x rarr 0)(lim) ((e^(x)-1)/(x)) is

At 40^(@)C , the vapour pressure in torr of methyl and ethyl alcohol solutions is represented by P = 119 X_(A)+135 , where X_(A) is mole fraction of methyl alcohol. The value of (P_(B)^(@))/(X_(B)) at lim X_(A) rarr 0) , and (P_(A)^(@))/(X_(A)) at lim X_(B) rarr 0 are:

At 40^@C the vapour pressures in torr, of methyl alcohol ethyl alcohol solutions is represented by the equation. P=119X_A + 135, where X_A is mole-fraction of methyl alcohol, then the value of lim_(X_(Ararr1)) P_A/X_A is:

At 40^@C the vapour pressures in torr, of methyl alcohol ethyl alcohol solutions is represented by the equation. P = 119X_A + 135 where X_A is mole-fraction of methyl alcohol, then the value of lim_(X_Ararr1) P/X_A is :

At 40^@C, the vapour pressures (in torr) of methyl alcohol (A) and ethyl alcohol (B) solution is represented by: P=120X_A + 138, where X_A is mole-fraction of methyl alcohol, then the value of lim X_A rarr 0 P_B^@/X_B and lim X_B rarr 0 P_A^@/X_A are:
