The value of the equilibrium constant, Kc, at a certain temperature is 4.00 x 10-1. Would the reaction as represented by the chemical equation favor reactants or products? Enter P or R. N2(g)+3H2(g) = 2NH3(g)

college chemistry
At 625 K the value of Kc for the equilibrium represented by the balanced equation is 2.50 x 100. Calculate the value of Kp at the same temperature. Express answer in scientific notation. 2NH3(g) = N2(g)+3H2(g)

i don't understand..

college chemistry
If the initial concentration of F(g) is 8.285 mol/L, calculate the % decomposition of F(g) when the reaction comes to equilibrium according to the balanced equation. The value of Kc at 927.0 °C is 370.00. The initial concentration of the reaction products is 0 mol/L. 2F(g)...

thank youu!
