P1 and P2 are respectively `:`

Let f(x, y, c_1) = 0 and f(x, y, c_2) = 0 define two integral curves of homogeneous first order differential equation. If P_1 and P_2 are respectively the points of intersection of these curves with an arbitrary line, y = mx then prove that the slopes of these two curves at P_1 and P_2 are equal.

At some temperature N_2O_4 is dissociated to 40% and 50% at total pressure P_1 and P_2 atm respectively in NO_2 .Then the ratio of P_1 andP_2 is :

N_2O_4 is dissociated to 33% and 40% at total pressures P_1 and P_2 atm respectively. Hence, the ratio of P_1 to P_2 is

N_2O_4 is dissociated to 33% and 40% at total pressure P_1 and P_2 atm respectively. Then the ratio P_(1)//P_(2) is

N_2O_4 is dissociated to 33% and 40% at total pressure P_1 and P_2 atm respectively. Then the ratio P_(1)//P_(2) is
