Given an equilibrium constant value of 7.2 x 10-4 it is false to say that the reaction proceeds essentially to completion.
<h3>What is the equilibrium constant?</h3>
In a reaction, we can judge using the value of the equilibrium constant weather or not the reaction moves on to completion. If the reaction moves up to completion, it the follows that the value of the equilibrium constant ought to be large.
On the other hand, when we have a case that the equilibrium constant is small and is not so large, then the reaction does not proceed essentially to completion.

Explanation:
Given parameters:
Heat of fusion of water = 6kJ/mol
Mass of ice = 1850g
Unknown:
Quantity of heat required to melt ice = ?
Solution:
The quantity of heat required to melt the ice must be capable of overcoming the heat of fusion of the ice.
First convert the given mass to number of moles;
Number of moles of water = 
Molar mass of H₂O = 2 + 16 = 18g/mol
Number of moles of water = 
= 102.78mole
Now to find the quantity of heat;
Q = number of moles x heat of fusion of water = 102.78 x 6
Q = 616.67kJ
