For the reaction, (2 NH ₃(s)+ CO ₂(g) NH ₂ CONH ₂(a q)+ H ₂ O (t) ), find the value of equilibrium constant at 295 K. Given, standard Gibbs energy change at the given temperature is (13.9 kJmol ⁻¹ ).
Options
- A(2.88 10^2 )
- B(2.58 10^2 )
- C(2.40 10^2 )
- D(2.65 10^2 )
Correct answer
A. (2.88 10^2 )
Step-by-step solution
( aligned & G^ =-2.303 n R T K_C & -13.9 10^3 ~J =-2.303 1 8.314 295 K_C & K_C= -13.9 10^3 -2.303 1 8.314 295 =2.46 & K_C=10^ 2.46 288.4=2.88 10^2 aligned ) Hence, option (a) is correct.
