For a gaseous phase first order reaction 4 ~A ( ~g ) K B ( g )+6 C ( g ) the rate constant is given by K = 1 Pt ( QP ₀ R P ₀- SP _ t ) when expressed in simplest whole numbers, where P ₀ is the initial pressure of ' A ' and P_t is the total pressure at any time ' t '. Report the value of (R+S)-(P+Q) .

Correct answer

4

Step-by-step solution

aligned & 4 A B+6 C & P₀-4 x & P_t=P₀+3 x x= ( P_t-P₀ 3 ) & 4 K t= ( P₀ P₀-4 x ) & = P₀ P₀- 4 (P_t-P₀ ) 3 & = ( 3 P₀ 7 P₀-4 P_t ) & K = 1 4 t ( 3 P₀ 7 P₀-4 P_t ) & P=4, Q=3, Q=7, S=4 & (R+S)-(P+Q)=11-7=4 aligned
