Methyl alcohol can be prepared commercially by the reaction of hydrogen with carbon monoxide. Under equilibrium conditions at 7.00 × 102 K,
[H2] = 0.0720 M, [CO] = 0.200 M, and [methanol] = 0.0300 M. Find the value of Kc, and then find the value of Kp. What is the value of Kp?
1. 1.05 × 10-6 4. 4.39 × 10-2
2. 7.33 × 10-6 5. 8.76 × 10-3
3. 1.14 × 10-1 6. none of the above
I found the value of Kc to be 28.9. I know to convert Kc to Kp, the equation is Kp=KC(RT)deltaN
I thought that deltaN may be the stoichiometric coefficients from the equation Co+2H2-->CH3COH, like products-reactants and when I do that I get -2. If I plug all those values in I get 28.9(8.314*700)^-2, which is 8.53*10^-7. Am I doing something wrong? I know it could be none of the above, i'm nervous that it isn't close to any answers.
