Question

Consider the reaction: A(g) + ^B(g) 2C(g) You may want to reference (Pages 587-592) Section 14.3 while completing this problem. - Part A Identify the expression for the rate of the reaction with respect to each of the reactants and /A AB rate- AA rate -2 - Correct To have a single rate for the entire reaction, the definition of the rate with respect to each reactant and product must reflect the stoichiometric coefficients of the reaction. Upon inspection, for every mole of A that reacts, one-half mole of B reacts, and two moles of C are formed. The relative rates according to the reaction stoichiometry are rate =- . Part B When C is increasing at a rate of 2.5x10 M-s-1, how fast is B decreasing? Express your answer using two significant figures A/B .|-75-10 3 X Incorrect; Try Again Part C How fast is A decreasing? Express your answer using two significant figures

Explanation / Answer

Part B-

Delta[C]/delta t = 2.5*10-2M/s

2delta[B]/deltat = 1/2delta[C]/deltat

= 1/2 * 2.5*10-2M/s = 3*10-2 M/s

delta[B]/deltat = 3*10-2/2 M/s = -1.5*10-2M/sec
