Hello everyone, let's start the question.
00:03
In this question we are given with a red of reaction taking place between lithium, positive ion and aluminium, for which the reaction goes as 3 times of lithium positive ketion in aqua state when reacts with aluminium metal, that is aluminium solid, it produces 3 times of lithium positive ketion in aqua state when reacts with aluminium metal, that is aluminium solid, it produces 3 times of lithium metal that is lithium solid and aluminum metal gets oxidizes into plus three oxidation state and it is an aqua state.

Now for this particular reaction taking place we are given with the standard gift free energy value which is equal to 402 .2 .23 kilojoules we are asked to calculate to calculate the value of kc that is equilibrium constant.
01:10
This is to be calculated in this case.
01:14
So we will be using the relation by using the relation between gipz -3 energy and the equilibrium constant that delta g0 is equal to negative 2 .303 multiplied by r, multiplied by t, multiplied by log kc on substituting all the values here we can easily calculate the value of kc now delta g -not is given as 402 .23 kilojouze it is equal to negative 2 .303 multiplied by the gas constant here are stands for gas constant and this is t t stands for the temperature and k c stands for the temperature and k c stands for equilibrium constant.
02:13
Kc is equilibrium constant.
02:17
And delta g0 is standard give free energy change.
02:30
Pre energy change...
