Question

For the first order gas phase decomposition reaction, 

A(g) → B (g) + C (g)

if P₀ is the inital pressure of A and P₁ is total pressure after time t, then

a. \(k =\frac{2.303}{t}log\frac{p_0}{P_t}\)

b. \(k=\frac{2.303}{t}log\frac{p_0}{p_t -p_0}\)

c. \(k =\frac{2.303}{t}log\frac{p_0}{P_t-2P_0}\)

d. \(k =\frac{2.303}{t}log\frac{p_0}{2p_0 -P_t}\)

Answer 1

 d. \(k =\frac{2.303}{t}log\frac{p_0}{2p_0 -P_t}\)
