So, let's start the equation.
00:02
The question state that we have given a equation that so2 plus half molecule of oxygen to form sulphur trioxide.
00:13
All the three molecules are in the gaseous form.
00:16
So, we'll take g here.
00:18
On balancing the equation, on balancing the chemical reaction, the chemical reaction, we get twice of so2 plus o2 to form two molecules of so3.
00:37
That means, when we solve for the heat reaction or the amount of heat revolved, then delta h will be equal to the summation of delta h of products of products minus the summation of delta h of reactants of reactants.
01:03
That means, solving, we get delta h, delta h will be equal to 2 moles of minus 396 kilojoule per mole minus 2 moles of minus 297 kilojoule per mole plus 1 mole of oxygen...
