briefly explain the meanings of the following terms as they relate briefly explain the meanings of the following terms as they relate briefly explain the meanings of the following terms as they relate only D) I and II only E) I, II, and III 43) For the reactio n 2A+3B+ C-Products, the rate equation is: B) R k[A][B][C] C) R = k[A]2[B][C] = k[B]"[C] sufficient information to fix rate equation 44) For a certain first order reaction, it is found that it takes 156 secor reactant to fall from 0.100 M to 0.0500 M. How much time would it t reactant to fall from 0.0500 M to 0.0250 M? A) 156 seconds B) 76 seconds Rentoul Rote5 12 seconds O) 12.5 seconds

Explanation / Answer

Ans 44 : C) 312 seconds

Since the reaction is first order reaction , the rate of reaction will directly depend on the concentration of reactant species.

So if the concentration has become halved from 0.100 M to 0.0500 M in 156 seconds , it will further reduce to 0.0250 M in next 156 seconds.

So the total time will be 156 + 156 = 312 seconds.
