The irreversible reaction is carried out in a reactor that initially contains 2.5 m3 of solution with a concentration of 1 kmol of A per cubic meter of solution. A solution containing 0.50 kmol of A/m3 enters the tank at a rate of 10 m3/h and is mixed perfectly with the existing solution. The resulting product solution leaves the reactor at 5.0 m2/h. The reaction is first order with k = 0.2 hr"1. Calculate the initial da/dt. A. - 2.4 kmol/(h·m2)
B. - 2.6 kmol/(h·m2)
C. - 2.8 kmol/(h·m2)
D.- 2.2 kmol/(h·m3)
E. None of the given answers.

sorry to disappoint you but i’ve been using for years and never once have i seen a “live section.” i’m sorry and i hope this !

answer:

// here is code in C++.

#include <bits/stdc++.h>

using namespace std;

//main function

int main()

{

  // variable

 int n;

 cout<<"enter a number:";

 // read the input

 cin>>n;

 // find the square root of the absolute value

 float square_root=sqrt(abs(n));

 // print the square_root

 cout<<"square root of "<<n<<" is: "<<square_root<<endl;

  return 0;

}

Explanation:

Read a number from user and assign it to "n".Then find its absolute value with abs() function.Then calculate the square root of the absolute value with sqrt() function.Print the square root of the number.

Output:

enter a number:-17

square root of -17 is: 4.12311
