A per second. What is the chemical reaction rate with respect to product C.
A. 0.25 M C /s
B. 0.50 M C / s
C. 1.0 M C/ s
D. -1.0 M A/s
E. -0.50 M C / s
Suppose that we were measuring the average rate of reaction for 1A+2B=1C and that we obtained a value of -0.50 M ?

When 1 M of A is consumed, 1 M of C is produced.
When the rate is -0.50 M of A per second (the negative sign indicating that the concentration of A is decreasing), the rate is also +0.50 M of C per second (the positive sign indicating that the concentration of A is increasing).
...... The answer is : B. 0.50 M C / s
