- Q6If a dynamic equilibrium is disturbed by changing the conditions, the position of equilibrium moves to counteract the change. Who's state this principle?Le DéjeunerLe Verbe AllerLe ChatelierLe Flamenco30s
- Q7What is the effect of changing the concentration of the substances present (by adding more A (or B)) to increase the product?The reaction will remove the extra A by producing more C and DThe reaction will remove whole of B by producing more C and DThe reaction will remove whole of A by producing more C and DThe reaction will remove the extra B by producing more A and C45s
- Q8What is the effect of changing the concentration of the substances present (by continuously removing C (or D)) to increase the product?The reaction will react more B and C to replace the C that is being removedThe reaction will react more C and D to replace the A that is being removedThe reaction will react more C and D to replace the C that is being removedThe reaction will react more A and B to replace the C that is being removed45s
