consider the reaction : 3A (g) + 2B (g) = 4 C (g) a ) determine the expression for the rate of the reaction with respect to each of the reactants and products ? b ) when ( C ) is increasing at a rate of 0.043 M/s , what is the rate of the reaction ? c ) when ( C ) is increasing at a rate of 0.043 M/s . how fast is ( A ) decreasing ? please explain
