at 10​​ degree celcius the osmotic pressure of urea solution is 500mm. the solution is diluted and the temperation is raised to 25 degree celcius ,when the osmotic pressure is found to be 105.3mm.the extend of dilution is?

In the reaction A + 2B ⇌ 2C, if 2 moles of A, 3 moles of B and 2 moles of C are placed in a 2 L flask and
the equilibrium concentration of C is 0.5 mol/L. The equilibrium constant (KC) for the reaction is.....and please tell how you know that the reaction is going forward .. imean how to calculate the reaction quotient ???
