🤓 Based on our data, we think this question is relevant for Professor Balasubramanian's class at New Jersey Institute of Technology.
Recall the equation used for a zero-order reaction:
k = 1.20x10-4 mol/(L·s)
[HI]o = 0.250 mol/L
Calculate amount of HI at 25 min:
The decomposition of hydrogen iodide on finely divided gold at 150°C is zero order with respect to HI. The rate defined below is constant at 1.20 x 10-4 mol/L•s.
a. If the initial HI concentration was 0.250 mol/L, calculate the concentration of HI at 25 minutes after the start of the reaction.
