Completely inappropriate and only further insinuates your ignorance...You should be ashamed of yourself. Grow up and get a life those comments should be kept to yourself.

Chem
For the reaction I2(s)+Cl2(g) ==> 2ICl(g) delta H= 36kJ, delta S= 158.8J/K at 25° C. Calculate the temperature at which Keq is 4.0*10^3. delta G= (delta H)- T(delta S) = 36 - (298)(0.1588) = -11.32 delta G= -RTlnK -11.32= -8.31Tln(4*10^3) -11.32= -6892.35 T T= .00164 &g...
