5. The following mechanism is proposed for the reaction between hydrogen and iodine monochloride: Step 1: H2 + ICl→HI + HCl Step 2: HI + ICl→I2 + HCl
a. Write the balanced equation for the overall reaction. All components are gaseous.
b. Identify any intermediate(s) and/or catalyst(s) in the reaction.
c. If the first step is slow, what would you expect to be the rate law for the overall reaction?
d. If the second step is slow, and the first step is fast and reversible, what do you expect to be the rate law for the overall reaction?
e. If the following data were obtained, which mechanism is supported? Explain.
Time (s) 0
50.0 100.0 200.0 300.0
[ICl] (M) .01000 .00787 .00649 .00481 .00380

the mass of the cathode increases because ions from the solution get reduced to atoms and become part of the cathode.

c, liquids evaporate, creating a gas

the answer is 1260

you spend 7 hours in school for 1 school day with 5 school days in 1 school week with 36 school weeks in a school year.

7*5*36= 1260 it's all about multiplying

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
