I got this question wrong on my homework. The teacher did notgiveus the answer nor explain to us how to do this. With thegiveninformation I don't know how to solve this.

I need to know how to solve this kinds of problem,,,

Please help me!

Thank you

I would like to know how to solve this:

For the reaction 2 A + B ---> 3 C, the instantaneous rate for A at a moment is –0.010 M/s.

a)At the same moment, what is the rate for B?

b)At the same moment, what is the rate for C?

c)Would the initial rate of production of C be greater than or less than your answer to part b?
