An organic compound undergoes first-order decomposition. The time taken for its decomposition to 1 / 8 and 1 / 10 of its initial concentration are t_ 1 / 8 and t_ 1 / 10 respectively. What is the value of [ t_ 1 / 8 t_ 1 / 10 ] 10 ? ( ₁₀ 2=0.3 )
Correct answer
0
Step-by-step solution
array l t_ 1 / 8 = 2.303 8 k = 2.303 3 2 k t_ 1 / 10 = 2.303 k 10= 2.303 k [ t_ 1 / 8 t_ 1 / 10 ] 10= ( 2.303 3 2 k ) ( 2.303 k ) 10=9 array
