Question

For the gas phase decomposition of phosphine at 120 °C:

\[ 4 \text{PH}_3(g) \rightarrow \text{P}_4(g) + 6 \text{H}_2(g) \]

The average rate of disappearance of \(\text{PH}_3\) over the time period from \( t = 0 \, \text{s} \) to \( t = 28 \, \text{s} \) is found to be \( 3.18 \times 10^{-4} \, \text{M s}^{-1} \).

The average rate of formation of \(\text{H}_2\) over the same time period is \(\_\_\_\_\_\) \( \text{M s}^{-1} \).
