For the reaction SnO2(s) + 2H2(g) = 2H2O(g) + Sn(l) at 900 K the equillibrium steam hydrogen mixture was found to be 40% H2 by volume. The Kp is(a) 1.15 (b) 2.25 (c) 7.75 (d) 10
In the reacn. SnO2(s) + 2H2(g) = 2H2O(g) + Sn(l) Since solid and liquid states compounds would not take part in Kc or Kp. Hence, from chemical eqn., SnO2(s) + 2H2(g) = 2H2O(g) + Sn(l) t=0 V ...
