ICI reacts with H2 in the gas phase according to the following chemical equation: 2ICl(g)+H2(g)I2(g)+2HCl(g) It is observed that, when the concentration of H2 is reduced to 1/2 of its initial value, the rate of the reaction is reduced to 1/4 of its initial value. When the concentration of ICl is multiplied by 9.48, the rate of the reaction also increases by a factor of 9.48. (a) Write the rate expression for this reaction, and give the units of the rate constant k,assumingconcentrationisexpressedasmol-1 and time is seconds ratekunits== (b) If [ ICl] were multiplied by 3.21 and [H2] by 2.33, what change in the rate would be observed? The rate would increase by a factor of 3 item attempts remaining
