To find the instantaneous rate at t=5 s, we need to draw a tangent line to the curve at t=5 s and calculate the slope of that line. The slope of the tangent line gives us the instantaneous rate of reaction.

From the graph, we see that the tangent line at t=5 s will be approximately parallel to the x-axis. Therefore, the slope of the line will be close to zero. Looking at the scale on the y-axis, we see that the slope is around -0.02 M/s. Since we need the rate in the positive direction, we take the absolute value and get 0.02 M/s.

Therefore, the best choice is C) 0.02 M/s.
