A Student Determined the Equilibrium Concentration in the Following Equation $\times$

Question 91

Multiple Choice

A student determined the equilibrium concentration in the following equation by neglecting the x term in the denominator.Was the student justified in this approximation? Why or why not? K = 4.0 $\times$ 10^-² = $A student determined the equilibrium concentration in the following equation by neglecting the x term in the denominator.Was the student justified in this approximation? Why or why not? K = 4.0 \times 10<sup>-</sup><sup>2</sup> = A) Yes,the concentration > K,so the x can be ignored. B) Yes,the value of x determined in this way is less than 0.05,so it can be ignored. C) No,the value of x determined in this way significantly reduces the denominator. D) No,the value of x can never be ignored in solving an algebra problem. E) No,the value of K is much less than 1 so x cannot be ignored.$
