Question

Calculating reaction rates?

Answer 1

This is the question. Not sure what to do.

Answer 2

I think that the requested rate \(r\), is given by the subsequent computation:
\[r = \frac{{0.0070 - 0.0029}}{{700 - 200}} = ...?\]

Answer 3

.0069942?

Answer 4

My bad, I used your expression and got a right answer of .0000082.

Answer 5

I got this:
\[\Large r = \frac{{0.0070 - 0.0029}}{{700 - 200}} = 8.2 \cdot {10^{ - 6}}\]
