Defined Dalton\'s law |
| Answer» Dalton’s law of partial pressures is a gas law which states that the total pressure exerted by a mixture of gases is equal to the sum of the partial pressures exerted by each individual gas in the mixture. For example, the total pressure exerted by a mixture of two gases A and B is equal to the sum of the individual partial pressures exerted by gas A and gas B (as illustrated below).<br>the total pressure exerted by mixture of non-reactive gases is equal to the sum of partial pressure of each gas present in the mixture under the same conditionss of T and V. | |
