Consider the reaction: 3 a + 5 b --> 4 c. the rate of the reaction is found to be .7511 m/s. what is the rate of change of b? be sure to consider whether the substance is disappearing or appearing in your answer.

-3.7555 M/s is the rate of change of B.

Explanation:

3A + 5B  → 4C

Given that rate of the reaction ,R= 0.7511 M/s

Rate of the reaction is defined as change in concentration of any one of the reactant or product with respect to time.

The negative sign indicates the concentration of reactant B is decreasing with progress in time. This mean reactant B is disappearing.

-3.7555 M/s is the rate of change of B.
