For the equilibrium , H2O(g) + CO(g) H2(g) + CO2(g), Kc = 24 at 500 K. Suppose 0.0100 M H2O, 0.0200 M CO, 0.0300 M H2 and 0.0400 M CO2 are placed in a reaction vessel at 500 K. Is the reaction mixture at equilibrium? a. Yes, Q = K and the system is at equilibrium. b. No, Q > K and the reaction will consume products to make more reactants. c. No, Q > K and the reaction will continue to make more products. d. No, Q < K and the reaction will continue to make more products. e. No, Q < K and the reaction will consume products to make more reactants.

00:01 Hello hi students let me explain you the question here so in this particular reaction equilibrium so the equilibrium of a reaction that is h2o gas plus co gas plus h2 gas so means h2o gas plus co2 gas it gives rise to h2 gas plus co2 gas this is the reaction so this particular reaction for the equilibrium the equilibrium constant in terms of concentration it is equal to 24.

00:36 Like that is 500 kelvin's okay so here suppose 0 .0100 molar water so water and 0 .02 molar carbon monoxide 0 .03 zero zero molar hydrogen and 0 .0400 molar hydrogen and 0 .04 4 -0 molar carbon dioxide.

01:01 So they are placed in the reaction at 500 kelvin's.

01:06 Is the reaction mixture at equilibrium? so whenever we place these concentration in the particular chemical reaction, the reaction mixture at equilibrium, what happens to the reaction mixture at equilibrium? at equilibrium.

01:24 At equilibrium.

01:25 So here they have given so many options okay among these is the correct option so first of all we have to write the equation here that is h2o plus you so gas even with the water also it is in the form of vapor use rise to hydrogen gas let's co2 gas okay and the equilibrium constant 24 at 500 kelvin's okay okay this is the information and here water it is 0 .01 and carbon monoxide it is 0 .02 hydrogen it is 0 .03 carbon dioxide 0 .04 okay we know that caution this is reaction quotient that is equal to product concentrations by reactant concentration.

02:25 So is q reaction quotient that is equal to product concentration divided by reaction concentration that is equal to h2 concentration into co2 concentration that is divided by h2 concentration into co concentration so simply we have to substitute the values here so the values are 0 .03 into 0 .04 divided by 0 .01 into 0 .02 that is equal to 0 .001 2 divided by 0 .002 that is equal to 6.

03:09 So here actually the kc value it is 24...
