So in this question we are given equation that a plus 2b gives c where a is 2 moles b is 5 moles placed in 1 litre container and concentration of c is 0 .148 mole per liter.
00:32
And we have to find kc for the reaction.
00:39
First we will find the initial concentration of a, that is number of moles upon volume of solution, which will be equal to 2 mole.
00:58
2 mole per liter and concentration of b will be 5 mole divided by volume that is 1 litre.
01:08
This will be equal to 5 mole per liter.
01:15
Now making the ice table for the reaction, that is, finding the initial concentration, the change and the equilibrium concentration.
01:35
So, initial concentration of a is 2, b is 5 and c is 0.
01:48
X 2x and x where the reactant concentration is decreasing and the product concentration is increasing so the equilibrium concentration will be 2 minus x 5 minus 2x and x so concentration of c is x we are given already that x concentration of c is 0 .148 mole per liter.
02:26
This is the value of x...
