Question
Initially, the container contains only H2 and I2 gas molecules. Describe the movement of the molecules and consider whether or not they interact.What will you see as the molecules react?
Assume that equilibrium is achieved within 15 minutes. Describe what you will see once the reaction hasachieved equilibrium. Can you tell from the information given whether there will be more reactants or moreproducts at equilibrium?
What will you see 20 minutes after the reaction has achieved equilibrium? Will this situation be different from what you will see 2 minutes after the reaction has achieved equilibrium? If so, how?
Explanation / Answer
movement of the molecules will be random motion , the iteraction will take place when the molecules collide.... as hydrogen has 1 valence electron and iodine has 7 , so they will interact to complete their duplet and octet respectively , an activated complex of high energy is formed as a result as the molecules react... HI is formed H2 + I2 = 2HI the reaction is exothermic, hence it will be observed a rise in temperature with the given information we can't tell which will be more as it depends on the equilibrium constant the situation will be same after the equilibrium is achieved whether it is 2 min or 20 min , reactants will convert into products and products into reactants but overall situation will be same
