Enter the reaction The rate of disappearance of IO_3^-(aq) at a particular time

Question

Enter the reaction The rate of disappearance of IO_3^-(aq) at a particular time and concentration is mol/(L middot s). What is the rate of appearance of I_2 (aq)? A) 2.5 times 10^-3 mol/(L middot s) B) 7.5 times 10^-3 mol/(L middot s) C) 8.3 times 10^-3 mol/(L middot s) D) 1.2 times 10^-3 mol/(L middot s) E) -7.5 times 10^-3 mol/(L middot s) What type of colloid is formed when a gas is dispersed in a solid? A) sol B) gel C) aerosol D) emulsion E) foam For a reaction of the form A rightarrow products, a plot of 1/[A] versus time is linear for which order? A) second B) fourth C) third D) first E) zero

Explanation / Answer

Answer: 3) E) Foam

Foam is formed when gas particles are trapped in aliquid or solid

4) A) second

I n second order reaction, The plot between 1/[A] versus t (time) give the staright line.
