To calculate the temperatures where a decomposition will become spontaneous, we first need to calculate delta s.
00:08
They tell us that delta g is equal to 37 .18 kilojoules per mole.
00:18
Delta g is going to be equal to delta h, which they tell us is 92 .5 kilojoules per mole, minus t delta s.
00:32
This delta g has this value at 25 degrees celsius, which is 298 kelvin, and then that's multiplied by delta s.
00:42
So delta g equals delta h minus t delta s.
00:46
That's an equation that you should know.
00:49
Solving for delta s, we get 0 .186 kilojoules per kelvin.
01:00
So now to determine the temperatures at which it's spontaneous, we'll first determine.
01:04
Determine the temperature at which it's neither spontaneous nor non -spontaneous and delta g is zero...
