Thermodynamics
2Na(s)+ 2H2O(g)--------> 2NaOH(s)+H2(g)
1. Determine the temperature of the products when the second reactant in the equation is 20% in excess of theoretically required and the consumption of the limiting reactant is complete.
2. Repeat (1) however, assume that 80,000 J of heat leaks into the surroundings.
Standard Heat of Reaction @298K = -367,582 J
