At 25°C, hydrogen iodide breaks down very slowly to hydrogen and iodine: rate = k[Hlf The rate constant at 25°C is 2.4X 10-21 L/mol-s. If 0.0100 mol of HI(g) is placed in a 1.0-L container, how long will it take for the con­centration of HI to reach 0.00900 mol/L (10.0% reacted)?

Ithink 2 is the correct

Answer246 k;

I’m not sure about this question

The question is incomplete. complete question is attached belowanswer: correct answer is option b  i.e.  solid particles  reason: filter paper has small pores, through which smaller particles can pass through. however, solid particles  have relatively larger size. hence, they are least likely to pass through.
