Finding temperature

Postby melissa_dis4K » Mon Jan 21, 2019 9:35 pm

For the following question how am I supposed to find the temperature to convert the given partialpressures into concentrations knowing that concentration= P/RT?
Self-Test 11.10A The initial partial pressures of nitrogen and hydrogen in a rigid,
sealed vessel are 0.010 and 0.020 bar, respectively. The mixture is heated to a temperature at which K " 0.11 for N2(g) + 3 H2(g) <---> 2 NH3(g). What are the equilibrium partial pressures of each substance in the reaction mixture?
[Answer: N2, 0.010 bar; H2, 0.020 bar; NH3, 9.4 & 10$5

I don't think you need to convert to concentrations because the answers seem to be in bars. You can just carry out the calculations in terms of pressure and Kp.
