Answer to Question #253795 in Algebra for atenz

Question

A reversible chemical reaction combines A and B to produce C and D according to

A+2B\underset{k_2}{\overset{k_1}{\rightleftharpoons}} C+ D. At equilibrium, A, B and C are present in concentrations 1 M, 0.05 M, 500 mM respectively. If the rate constants are k1=2M−2s−1 k1=2M−2s−1 and k2 =1M−1s= −1 k2=1M−1s−1, what is the concentration of D in M at equilibrium? Give the result to three significant figures.

Answer 1

2M+M+x=M

x=-2M

k3=-2M+2s+1
